A kit cost in the neighborhood of $100-$120 and includes 4 1 liter bottles of liner and a can of hardener. You add hardener to the liter bottle, shake it up and spray it. The gun will run you between $15-$20. I needed more than a single kit since I'm spraying underneath as well. If you are just spraying inside the tub a single kit should be enough.

Small update (sorry no new pics). So I'm pretty much done with the trailer with the exception of the lid. The lid won't be a huge expense but I'm out of funds for a couple weeks until I can get another sheet of 16ga and a couple other peices for the lid frame. But the trailer is useable and I've dragged it around a few times just to see if I can find any issues.
Well one came up. I took it out on Sunday and and jacknifed it (on purpose) but did something stupid. I knew I was going to jacknife it and was waiting for the sound of the tongue bottoming out against my rear bumper and took my eyes of the mirror for a second. Well it turns out that the way my rear bumper is trimmed up toward the outside corners allows the tongue to not bottom out against the bumper but actually slide underneath the bumper. That, along with the lock-n-roll that allows it to rotate past 90* I jacknifed it a little too far and the top lip of the trailer tub came in contact with my rear fender flare on the Cruiser. Not a big deal (other than a crack in the fiberglass flare, since I wasn't paying attention), but I need to figure out a way to keep the trailer from over-rotating in a jacknife situation which will definitely need to happen from time to time on the trail.
Kinda hard to see from this picture but maybe you can see how my rear bumper slopes up (bottom edge) toward the corners and that the level of the tongue can pass underneath. I'm looking for suggestions on a way to limit the rotation during jacknife situations. Any thoughts?
Edit: Maybe you can see the rear bumper better in this picture. I would have thought that the center portion of the bumper before it angles upward would contact the tongue but the distance of the point of rotation on the hitch away from the bumper face puts the tongue at an angle past 90* before the tongue contacts that center section of the bumper, letting the trailer tub come in contact with the truck.

So my thoughts are to weld a "stop" to the top of the tongue. Basically another peice of the tongue material boxed in on top of the tongue to contact the bumper as the trailer jacknifes. Once I get my cooler rack on the tongue that will probably contact the truck as well, but I don't want to damage the cooler or the cooler rack by using them as the "stop". Thoughts?
Attach your chains to your clevis points? It may be too much for those little chains.

The chains are actually decent strength but I still don't think they'll cut it as a real long term solution. I'll take a look at it but I think I'll have to do something else.
Did the handle hit/get bent when it swung over?
If you have to put it on the triangular tongue, you might as well make the space usable like a cooler rack. Just need to make the bottom strong enough to take the hit from jack-knifing.

No, the handle is nowhere close to hitting. Remember the handle is very close to where the pivot point is on hitch and that pivot piont is proably 8" back from the bumper.
It looks like the corner of the bumper would contact the tongue about halfway back on the traingulated part of the tongue. I need to measure again but my cooler I'll be using there might not be as wide as that part of the tongue so I might be able to just put a beefy stop into the rack for the cooler and be ok.
Putting some sort of stop on the tonge probally wont solve your problem. If you are cresting a ledge or hill, or at the bottom of a ledge, the tonge will still hit somewhere in a knife. If there are stops, those may do more damage. My only thoght is to move your pivot point farther out by extending the hitch from the cruiser. just my 2 cents...
just a shot in the dark..how about a back up camera or a proximity sensor that beeps?

Interesting point. Could actually be a problem, but if the trailer was jacknifed in a position where the trailer was uphill of the truck, I think the tongue would actually contact the bumper as it should and keep the trailer from hitting the truck. If the trailer was downhill of the truck in a jacknife situation then the box of the trailer will actually be leaned farther away from the truck and therefore may not make contact. The main issue is on flat ground, the tongue passes under the corners of the bumper and therefore a stop of some sort would help in those situations.
Looks like I'm going to have to test this out in different scenarios.
Sounds like you need to design a new bumper.

I've got it!
I'm just gonna hang a bunch of those big white hotdog shaped boat bumpers all over the trailer. That should do it.

That's it, I'm EFF'd
Haha, you're screwed. Why don't you just give me the trailer so you can get started on the new one?
