so my parents came over to see the grandkids and during that time they scouted out my 80. A few days later my mom calls me and asked how much I would sell it for and get it road worthy I just laughed and told her no. Then my dad came over and asked the same thing and got the same answer. So I started looking for one for them to buy. But they will need to pull it behind there motor home. Is there anyone who dose that with there 80 if so what do I have to do to it for them to do so. They do not want to put it on a trailer.
 
you will want to find something else then. if you dont have it on a trailer then you need to pull both drive shafts to be safe.
 
There are two or three threads on here depicting someone towing an 80. One person went into great detail about building a hitch for the front as well as lighting, brakes, and video cameras to watch the truck as they traveled. I always thought you could not flat tow a 4WD, but apparently, it has been done successfully with no apparent damage or ill effects.

Do a few searches for "Flat Towing an 80" or similar and see what you get.
 
You can take this info for what it's worth. I had a 95 Explorer and wanted to flat tow it behind my old motorhome. Upon research it was determined that you COULD if you overrode the system and put a neutral tcase modification in place (electronic on those). Transfer case in neutral the vehicle is towable. The concern comes into play with an AT and the possibility of the transfer case popping into gear, turning the trans - which can overheat since the pump wouldn't be running.

With that info, I started my search for an FJ40. I do pull my rear driveline on that to flat tow... just to be safe.
 
For flat towing, the key is driveline lubrication. On most vehicles, lubricating oil is only provided by the pump on the transmission which only turns when the engine is running, but not when being driven by the wheels only. I don't know about the 80 for sure on that. However, you should be able to leave the vehicle in 'P'ark and put the transfer case in neutral. This will minimize the running gear that is turning while towing. You'll still need to know for sure if the transfer case is OK being externally driven for long period of time like that.
 
Have pulled my 80 numerous time for miles on end behind my motorhome. T-Case in Neutral. The t-case has an internal pump. I used an IR thermometer on it after 100 miles and temp was cool (dont recall exact numbers).
 
I see no issues at all, rear pups were quite common on automatic years ago, it enabled you to tow start the engine, too many accidents had that taken out.

I would fit one of those anti theft devices with a BF lock. Locks the transfer in neutral, and know the lever cannot be moved.

I used to install drive line disconnects at my old work but the kits are $$$$$ and don't want to spend that. The next option was a fj60/62 or a newer 4Runner with the 3.4
 
As mentioned there are a few threads on this, the one @Delancy linked is a good one.

However, you don't say what their TV is. This is critical in making a decision on what can be towed. Most MHs have a 5K tow capacity. If you put an 80 on a trailer, you are about 7-7500. I know because I have towed many thousands of miles with my car hauler and 80s behind my diesel Excursion. Even flat towing, you are at 5K or more, depending on gear/accessories. And you never really want to max out your capacity when towing.

Here is a good article on what vehicles are "dinghy friendly" Dinghy Towing 2015 | Towing Behind a Motorhome or RV | Dave Smith Motors Jeeps are very friendly and a big reason why you see so many being towed.

Additionally, you may need to beef up the frame and install a better hitch. And you will definitely will want a BrakeBuddy - Braking systems for motorhomes towing a vehicle or something similar. SAFETY FIRST
 
I don't know enough about the transfer case in an 80, but I can say for certain that toyota minitrucks can NOT be flat towed with the transfer case in neutral. They use a gear in the front of the reduction box to sling oil throughout for lubrication and when the case is in neutral this gear is disconnected and the oil slining does not happen.

Someone that knows these cases better than I do would have to comment on whether we can use xfer case neutral with no problems.
