The problem with buying a new TT or FW and letting it sit is that your warranty will run out before you know if anything is wrong with it. As far as quality on TT and FW that,s just a **** shoot, in my opinion. I know fellas that have bought top of the line and had nothing but problems I also know folks that bought bottom of the line rigs and have had trouble free driving so that's just the name of the game. There are no perfect RVs there is always something you wish wasn't there or wish it was there. Look around find one you like and buy it. It could be a lemon or it could be a Jewel. Ether way there is something on it that will have to be fixed changed or added. That's kind of the name of the hobby. That truck you are looking at should be able to handle a pretty substantial FW if set up right. The 350 can be purchased with the same amenities as the 250 but the price gets up there in a hurry. Hope this helps a little and have fun setting up your rig.
