Take heed of the advice on tow rating and especially the cargo capacity of the truck and the tounge weight of the trailer loaded. I think in all cases you run out of cargo capacity (meaning what the trailer tounge will load the truck, well before the towing capacity of the truck is reached.
s far as quality, its mostly visual that is of concern, as every trailer/motorhome nomater how expensive will give you issues to deal with. A freind just bought a $700,000 mh this summer and it has spent more time int he shop than living in it. Name brand mh to boot.
If you don't have the patience for warrantee work, skill to fix, or $$$ to fix, suggest you stay with a tent. That said, I love my last few trailers, but non of them came without a few problems, most I could fix myself.
Good luck.
