Lol, there are lots of trucks on here making me want to burn money! If you are going to go down the offroad trailer rabbit hole, really do your research on them. I spent two years looking and comparing before I decided on the Off Grid Trailers Expedition 2.0.
I am a big fan of just "doing" with absolutely no knowledge on a topic and I enjoy wasting tons of time on "potential" ideas that usually result in a "botched" project.
So much so that after I saw your set up, I got an old ice fishing trailer for free. Gutted it entirely (tons of rotting wood) and took it down to the deck this weekend. Then drove it for about 1/2 a mile and watched it act as if it was on a trampoline bouncing behind (a bit on the light side).
I was thinking of making a "baby toy hauler" out of it: imagine a small "cabin" on the front, large enough for maybe a twin/full bed that will flip against the wall to pack other gear. Then sort of a "roofed porch" towards the back of the trailer, which will remain a flat deck (my 2-seater turbo rzr will be 1/3rd covered under the "roofed porch" and be transported on the back half. So when the rzr is off the trailer, there will be a flat deck "patio". I want to run 2x4's along the bottom and stain them a dark shade to look all fancy and ****, then the entire exterior will either be black steel, or some form of LineX. I think I want to keep the suspension where I can drop the axle (put in a small motor because hand cranking is for chumps) so this trailer could sit flat on the ground, but I think I need to beef that suspension up one way or another and get some beefier tires (and some bitchin' off road rims because why not). It has a 2" hitch which I want to get a bit bigger, but I am not sure about the feasibility on any of this.
Improving the drop suspension on this has proven to require more engineering than I expected, but I have been coming up with a few completely ridiculous ways of achieving something that should work. That is, if my completely biased, uneducated, and illogical daydreaming proves to be solid research. I also need to figure out how to do all of that and gain some more clearance on the trailer.
Another part of me wants to buy a baby gooseneck and do the same thing, but a pop-up style tent on the elevated flat platform. (Those smaller gooseneck trailers that have the raised flat-deck on the neck, and the larger deck behind). I figured out a few ways to get the clearance I would need with the gooseneck, but not a single one of them come near anything remotely close to finically acceptable/responsible. I will have to lie heavily to myself to justify this path.
Or scrap the entire idea, make the trailer fancy, and sell it. Then buy one that requires no work, or build one on a better platform. I don't know, I have raging ADHD and the idea changed 15 times while typing this....
