I never had a trailer with living quarters but I have seen a bunch. While they are very nice , I say buy a Motorhome. Reason being it's real comfortable , Has it's own power and water system and it can be used for more than a race weekend with the bud's. We use our 35' motorhome a lot ,for more than racing and I wouldn't have it any other way. My motorhome has the big block chevy 502 crate engine in it and tows it's butt off. I have never had a problem towing my trailer even in the mountians. It does have it's bad points like mileage and finding a place to turn around. Even with the drawbacks I couldn't imagine towing with anything else.
