Off Road Teardrop for heavy rockcrawling

Postby Duffdog » Sun Dec 06, 2015 10:26 pm

Hi there!

I'm new to the forum and have started to build a teardrop that I can off road with and also sleep in. I haven't seen many of those around. My specs for this trailer are as follows:

1: Trailer must be able to make it on the hardest trails possible
2: Trailer must survive a 6' vertical drop onto rocks with no damage
3: Trailer must be able to carry 1000 lbs on the roof
4: Trailer must have air conditioning/heat/solar power/propane/ (all normal trailer stuff)
5: I must be able to sleep in it

I had a leftover UTV trailer that I used to move from San Jose, so I was just going to use that. Luckily, the previous owner had swapped in 30" Jeep lift springs but left the wimpy 2000lb axle. First order of business was replacing that with a 6 lug 5200lb axle and springover kit for additional lift. That still was not enough lift so I made some 9" 410 stainless shackles to lift the leaves up even more.

Here I have finished the frame and the lift and have started doing the interior walls I figured that radiant barrier sheeting would have some R factor for insulation. I will also insulate the trailer as well.

What are you putting on the roof to require a 1000lbs limit? Going to make it awfully top heavy.

generator, gasoline, water, hi-lift jack, spare parts, solar panels, a boat, refrigerator. Remember this is heavy rockcrawling, so I may have to ford a 4' deep stream and put everything on the roof temporarily.

for fording, why not just put the stuff inside the tear? I've seen campers built for the outback that had watertight doors that covered the bottom of the normal doors to about half way up the door opening, just for fording.

Seriously? A 6' vertical drop with no damage? Did you mean a 6" vertical drop? :?

I would like to see the tow vehicle that is going to be used and take a 6' drop. that is a big drop, i would assume it wouldn't need to drop that far, it would just need a really good rear bumper and a receiver that will allow for high angles. Nothing should have to drop just need to be able to drag and with the weight you are talking you may have to put some extra tube across the back to drag the trailer down steep rocks.

may want to even take out the leafs and put coils in its place, get a bit more suspension travel. only problem i see is you are putting alot of weight up high, and for "heavy rockcrawling" that could be bad with stiff suspension. it will be a battle of suspension travel to keep level and body roll on corners.

From what I see on Expo there are very few who drag their tears over super rough stuff. Most just get out away, then set up a base camp.
The few who do moab type stuff have trailers with welded frames in the wall and roof.

Here is one of my trucks in action :D . Also, I'm planning on making a coupling that will let me drag the steel frame across a rock in case it flops over on its side temporarily

Right on, cool little buggy man.

This is my Offroad truck

About the pintle hitch. You don't find it noisy and clanky? I have one of those on my towable generator and its really kind of annoying. Do you use one of those cone/pintle adapter things?

Nice fullsize wheeler!

Anybody know a US dealer that sells the off road hitches?
