I have a few more buyers but it is hard because everyone wants specifics like "when" and "how much".

That is real easy to understand. Infact, I am having to temper my interest in a trailer as it looks like there are going to be a lot of lay offs where I work. Since I am a temp. contractor, I will be one of the first to go.

I have to keep reminding myself that $800 to $1000 is a lot of money when you don't know if you are going to have a job from month to month.

I really need to find a real job!
 
BMAN, let me know if there's anything I can do to help out, offroad trailers have been a running obsession for me for a long time, and I have tons of sketches, ideas, dimensions and pictures saved, not to mention the guinea pig in the garage! :)

I did, I was considering at the time starting over from scratch, but after the last round of mods (Junior 3.0), I think it's pretty much done, just need to hammer down some details.

It's tough to explain, but if you really want to use an M416 on serious (not ultra hard-core) trails, you're going to have to modify it quite a bit, and that is going to add to the expenses quick. I only paid $295 for my trailer, but if I had to pay $800+ just to *buy* the trailer, I wouldn't even consider it, at that point starting from scratch would be the only option.

The best modification I ever did to the M416 was extending the tongue by 24". This made it a completely different trailer, not only can I now see it behind the lifted Cruiser, but I'm actually able to back it up quickly and easily. Before, it used to jacknife as soon as you put the old beast in reverse, and there were a couple of tough trails where I whacked the crap out of the sides of the Cruiser trying to maneuver the trailer around and over obstacles.

i think the 416 style trailer is a good buy at $800 if you are happy with it AS IS. even though exiled has not disclosed his money and time spent, i am sure he could have bought one of the custom build 416 style trailer with cash leftover for that new paint job for princess. am i close??

Agreed 100%, $800 is fine if all you need is paint, new seals and 12-volt bulbs. But if you plan to use that thing offroad on anything more than dirt roads, you might want to consider other options. The biggest limitations I saw in the M416 for *my purposes* were:

1. Short tongue
2. Stock lights vulnerable
3. Stock height
4. Wheel bolt pattern
5. Axle width/track
6. Box dimensions
7. Flimsy fenders
8. 30 years of government use
9. Stock tires dry-rotted and unsafe

Point 2 can be addressed cheaply and easily by making triangle brackets out of sheetmetal and bolting the stock lights up by the fenders. Cost? Negligible. The stock height I initially addressed by changing the shackles on it; M416's use the same shackles as 1947-1974 Jeep CJ's, so you can get aftermarket extended ones (I used Daystars). A custom axle took care of points 5 and 6, I paid $125 in Phoenix at Arizona Trailer and Axle; this also took care of the height, since I designed the axle for a SOA to match the Cruiser's height. The fenders gave me grief, not only where they flimsy but they also mounted mostly to the body, and I was afraid to rip them off on a rock. More on this later....
The biggest issue I had with the trailer was the last point; although in pretty good shape overall, it still had about 20 coats of paint on it, to the point where some of the bolts on the body looked like round rivets, you couldn't even tell how many sides they had. The underside had this milspec undercoating that was peeling off, the wire harness was crumbling into dust, the lunnette had so much paint on it it no longer turned, and the grease nipple was covered in paint.

Now a caveat. When I first bought the trailer I was a poor college student, so Junior 1.0 wasn't exactly a well-funded project. Not a lot of free time, either, and I didn't even have a car at the time (importation papers for the Cruiser took the better part of a year to complete). I rented a sandblaster, did the trailer in the driveway of my roommate's parent's house, painted it with Rustoleum spray cans, used Wurth SKS to line the interior, wired it with generic trailer stuff from Autozone, and bolted an ammo box on the tongue.

The Wurth SKS turned out to be worthless, the trailer tires I was running terrible on the trail, the tongue way too short for an offroad trailer.

Enter Junior 2.0, a project embarked on while I was a graduate student at Thunderbird. Again, funds weren't abundant, but I had learned a lot from experience and wanted to make some fundamental changes. Lifted the trailer to match the Cruiser, which made a tailgate almost mandatory. I had gotten into long trips into the desert, so I wanted to be able to lock up the trailer at the campsite while I made side trips on the Cruiser...enter the lockable steel lid. Paul Porter really helped me out with the design and execution of both modifications, and I completed this part of the project by adding matching rims and tires, painting the trailer, and mounting a MARES expedition tent on the steel lid. Worked great for some time, but I was still dealing with the flimsy fenders, the short tongue, and now had a too-short landing gear that forced me to use the tent only when the trailer was hooked up to the Cruiser. Because of the short tongue, I couldn't open the bumper swingouts or drop the tailgate, which made it impractical in camp.

Used it, did a lot of camping, made it to Crown King from Lake Pleasant with the trailer in tow, completed Trail 42 (bad idea) with it, and took it on an extended Utah trip. Learned some more...

Spent a regrettable couple of years on the East Coast, using it only for the ocassional Cruiser event like the Fall Gathering, then moved to Offroad Hell (er, I mean, Central Texas). For the first time since I moved to the US, my budget grew past the "buy red meat or spend money on the Cruiser" stage, and I began to consider additional mods.

Enter Junior 3.0, the current iteration. With my friend Jason Kenne behind the welding mask, we replaced the stock fenders with much stronger ones made with bent tubing and sheet metal. Not only are they much stronger, they're also much lower profile and fit the bigger tires/rims much better. Extended the landing gear so that the trailer sits dead even when disconnected. Extended the tongue by 24", allowing the installation of a cooler rack in front of the tub (made to fit either a medium Action Packer or one of the new steel-banded Coleman coolers). I got a great deal for Scorpion lining (about halfway between Rhino Lining and Line-X), and chose light gray to keep the heat and dirt down. Finally, I rewired the whole trailer (still running the generic stuff from 1.0) with 7-wire semi stuff, in anticipation of adding some lights for the campsite.

There's a few details to finish, like adding a better handle to the steel lid (opening it is awkward because the fit is *TIGHT*), finishing a table I built to attach to one fender, adding the lights, installing the propane and water tanks that are sitting in my garage, and maybe adding a better light to the inside of the lid.

So yes, I've spent a bunch of money on it, but I've also redone things several times (part of the learning curve) and often had to compromise because of budget constraints. All told, I probably have about $2,500+ in it, but I could do it now for much less and make one further change, the only limitation still there. I would make the box 6-12" longer in length so I could sleep inside the trailer if I needed to. I'm only 6" tall, but that's still to tall to sleep comfortably inside it.

Now you know more about my trailer than my wife does...he, he! Questions?
 
Guys,
I'm bowing out of this one. Thanks for including this CA boy in the AZ group purchase. I've been doing some research while waiting for a firm price and pick-up location to be deterined...and found the following (it's a heep site, but covers a "conversion" of a M416 for trail use) :
http://www.jeepsonly.com/project1/m416.html

The quick and dirty details of what this guy spent for what I'd consider minimum improvements are as follows:
$650.00 - Acquisition cost (11/2002)
$ 25.83 - new axle ubolts, nuts and washers (4 total)
$15.72 - new frame ubolts (1/2 x 12 inches) (2 total)
$9.95 - spindle nut socket - to remove the big hub bolt (tool)
$18.64 - 1/4 ton Jeep Trailer Safety chains (pair, plus shipping)
$16.00 - AZ title transfer ($4 plus late fees for waiting to do it)
$7.71 - Giant safety chain bolt and misc pintle adapter bolts
$20.00 - 2 Used 15x8 wheels with 5 on 5.5 bolt pattern, spray paint and primer
$72.54 - 2 Used BFG Mud Terrains 31x10.50x15, mounted and balanced
$17.64 - POR-15 Starter Kit (undercarriage coating)
$9.30 - 100lb bag of copper slag for sandblasting (don't use silica)
$3.43 - 4 red reflectors (replacements)
$27.50 - replacement drain plugs (2) (eBay)
$34.50 - replacement shocks (2) (eBay)
$125.00 - Permanent ADOT registration (Arizona) - no renewals
$10.00 - new urethane shock bushings
---------
$1,063.76 Total so far

For me, it doesn't make sense cost-wise. I can easily get something custom made for $1200 to $1400 (assuming I match the costs listed here, I'd already be in for almost $1200, assuming a puchase price of $800).

Cheers.
 
I sense momentum slowly fading on the group trailer buy. Maybe it will pick back up if we can get some more solid numbers and details on shipping and stuff.

The canadian trailers are supposed to be in good shape-- and a better trailer than the M416s-- so I think the cost of fixing one up would be less. All I plan to do is replace the axle some day (so I can get six lugs and a spring over) and maybe extend the hitch. I think that can be done and still be good deal on a trailer.

Now back to custom trailers-- I recently bought a utility trailer from a company in Apache Junction-- Graverlys. They make a bunch different types of trailers. I showed the old guy some pictures of the trailers made by 4x4 trailers and asked if he could do something like it. He said he could, but he needed details. Like actual plans with numbers and everything.

I think that is what we are really lacking when it comes to trying to build custom trailers. We need plans-- something with enough detail-- so the builder can give us a real solid price quote.

We have BMAN's start on plans, but I think it was just a start.

I tried to contact 4x4 trailers-- asked if they sell would sell their plans and got no response. BTW, you can buy trailer plans on ebay for a bunch of different types of trailers-- from small utility trailers to gooseneck horse trailers --- but I have never seen one for a 4x4 type trailer.

We really need to restart the group buy custom trailer thread.

I'm interested in one or two, but I live in Maine. Anyway they can be shipped individually?

No, the point was to save money in shipping by sending one semi load of trailers to Arizona. I don't think that would do you any good. Besides, you live in maine, can't you just drive to Canada and buy one?

desertdude, I think I'm going to get a teardrop. That is just the ticket for me.

sjpitts, I called them today and they are in business- they said they are revamping a couple models but the prices are steep for me too.
 
Gotta laugh at this thread. Oh well, the topic remains interesting.

The teardrops are cool. I stumbled across the outback teardrop site a number of months ago and was leaning towards building one but decided to go the big route and get an Airstream instead. Anyway, his is a nice setup. Love the ammo can evap cooler!

My plans may only be a start right now but being in the business of drawing CAD drawing every day, they won't be simple starter ideas for long. I actually had a chance to do some work on a secondary design last week before I went out of town and I will bring the plans with me on Friday to the sonic cruise.
