That's a little like asking what is your favorite food; everyone has their own opinion. Without knowing the specific details it sounds like they probably have enough truck to handle up to the mid 30 foot length of trailer. Our approach was to vistit a two or three dealers and find something that appeals to us, and then do a lot of reading on that brand and style on the web. The number one deal breaker for me would be any new or used rig with "China Bomb" tires on it. The good news is that can be easliy fixed. You didn't mention anything about how much they wanted to put into this RV; new, almost new or a fixer upper, and that would of course make a world of difference. Just shop, shop, shop and read, read, read. JMHO
