Building my expedition trailer with raised RTT

piecemeal

New member
Hello!! I bought this trailer a number of years ago with the intention of eventually turning it into an expedition trailer. I've been slowly working on it and now I'm ready to fabricate some sort of deck or elevated lift platform for the tent. Anybody have any opinions on how to mount the RTT (either on a stable mount open cargo, stable mount on a lift cover, or open cargo with elevated platform)??

Here are some of the pics so far....

__________________________________________________________________________________________________________________________________________
The underside axle, springs, and recent sealant and bolts have all been coated with a later of the Eastwood rust encapsulator paint. The total weight on the trailer now as it sits is about 450-500 lbs (with tires mounted and spare). The trailer deck was replaced with 3/8" steel plate and the approximate floor dimensions are 44" x 72". The trailer has an old school lunette pintle hitch on it.

So, trying to decide how to mount my Hannibal RTT on this trailer. Any suggestions?? I was thinking something similar to the attached figure so I could use the trailer for hauling lumber or kayaks (maybe??).

3/8 steel plate :eek:?! Are you planning on loading boulders into that thing?
LOL!! No, but the big sheet of metal sheet was free and I needed a new floor. I think the trailer was originally designed to haul utility poles (hence the rounded things on the front and rear gate). There used to be a hook and chain system for keeping them in place on those "cradles" that I cut off. It's definately overbuilt, but it won't need cross braces for sure. I'm sure it's got about 125 un-needed lbs of metal in the thickness, but it was free. I'd feel safe mounting anything directly to that instead of the sides if that makes sense if that helps to determine an appropriate design.

our local steel yard sells square tubing in graduated sizes with several of them sized to slip into one another

similar to the 2" receiver hitch system

you might consider creating STAKE POCKETS on the corners kinda like in the corners of a pick up bed

then fab your tower w/ the size that fits into the pockets ± ?

if the pockets are on the inside the tower can rest on that flimsey bed plate ;-) w/ nothing but a simple pin to keep them from jumping out

if the pockets are on the outside the tower frame will need to be bolted in place

Are those the same tires you use on your rig?
No. I'd like to because they're chunky, but they're bias ply and they only come in two sizes (smaller and this one). Going to get something in 33 x 10 x 16. Just not sure what. I Cruuently am running BFG AT 31.5 x 12.5 x 15.

I didn't previously think about running them on the inside of the tub, but that's not a bad idea [since the deck is stout ;) ].

Hey, thats a measly 330 pounds. It will prove useful when somebody flies a rifledrone overhead.

:love::love:

Well, to be honest, it closely resembles how the PO of my rig rebuilt the tub of my tow rig (3/8" diamond plate steel on the floor and fender wells and 3/16" formed steel re-skinned body from the front cowl back to the rear). It's armored to the point that you could chuck a grenade under it and it MIGHT hop off the ground a bit, MIGHT.

Still need to mount spare tire and cut lunette and add receiver in the front for variable towing options.

Looks great! I originally had my tent mounted that high but on a rack that was quite a bit less stout than yours and I had terrible issues with it offroad. It was too top heavy and spent a bit too much time on 1 wheel. I ended up rebuilding the rack with linear actuators so it could be lowered for travel and raised for sleeping.

Thanks!! I patterned the design loosely off another dinoot trailer. The metal on the floor is 3/8" and those friggin tires are wicked heavy, so I HOPE I won't have issues with it being tippy. To get the tent to go up to it's full height, I use one of the scissor jacks and a bar that has a channel to raise it up. What kind of actuators are you using and what is the weight capacity they can push? I think the tent comes in somewhere at about 150 lbs as it's a heavy canvas Hannibal tent and the metal framing is another 50 lbs is my guess. Also, I quick checked your build thread and I have three of those solar panels like you have that I "acquired" for free. Where did you get the mounting hardware and slides for that? How is it holding up to being knocked around?

:)🍻
