I don’t think it matters what kind of trailer you go with. We used the super basic stock trailers to haul stock up logging roads because everything!!! I mean everything thats not welded on gets knocked loose. The best stock trailer everything thing was welded not a single screw or bolt and the only moving part rear door had welded pins in welded strapped gudgeons. The only un welded bolts were the lug nuts on the wheels lol.
Even the slightly more fancy stock trailer with a pass tru door at the front end the door latch broke off the first time we used it. For the next few years that door just had a rope holding it shut
.
All the windows in all of these RVs will rattle loose and leak getting towed down even typical logging roads. Absolutely ALL the fasteners will get shook loose. Hell the cheap ******** PEX water line stuff thats for stationary houses definitely won’t do well. Suspension? Mehh it will only delay the final outcome and not really by much given “hey I have $3000 suspension I’ll take it up there” ism will be greater than the guy rolling boring $1500 suspension that says na this is fine.. lol
