Give good thought and consideration about the extra add-ons they're going to try to sell you.. paint warranties and discount cards and stuff... in the end a lot of money-wasters, just extra income for the dealer.
Find a unit that meets your criteria... floor plan, features, construction materials, price, color.. spend some time on dealer websites browsing inventory to formulate an idea for what you want. Wife and I were able to narrow down dealers pretty quick just by how responsive OR UNRESPONSIVE they were.
Pick a couple of dealers and then go visit. Have your idea of what you want but be open-minded. We went to the dealer with two specific units in mind from their online inventory, but wound up looking at 7 units. If they listen to your criteria and can show you units that consistently fit within that criteria then they might be worth your purchase. If it seems like they're not listening to you or you have to keep reminding them about your budget or that you wanted rear living, maybe time to move on.
And lastly.. don't neglect your hitch.. depending on your tow vehicle you may want a weight distributing hitch. I'd encourage you to determine for yourself whether you need one, but if you have a half-ton for example you probably will want one. It'll make the drive a lot more enjoyable and a lot less white-knuckle. :-)
Cheers and good luck! Hope to see you on the road. Safe travels;
