I use a 16ft two axle Big Tex to mostly haul firewood and an occasional rig up to Dodge 3500 crew cabs. Only issue was the stock biased ply tires. Life has been great since those were replaced with the heaviest loads coming in at 7,000 lbs.
I've not had issues, but I don't care for the exposed wiring one finds on most trailers. If one has plans for getting off road and out there, it would be wise to rearrange the routing and durability of that system.
Ha I forgot to mention the wiring. Yeah, I rewired mine multiple times.
