Most likely a LOTTTT further then you want to go, but the county next to where I live, Lamar county Tx. seems to be the trailer factory capitol of the world. It is in the N/E part of Texas near the Okla. and Ark. borders. The 2 big plants are PJ trailers and Loadall trailers each with hundreds and hundreds of trailers in front of these factories. I'm told they will sell you one from the plant but I would check first. Then there are at least 50 smaller operations in the same area, these are usually guys who worked at the big plants and went out on there own. I know they sell from these smaller (1-20 man operations). They will also build one to your specs in about a week. The county seat is Paris Tx. but all the plants are in the rural part of the county. Just think of the stories you could tell your buddies about July heat in Texas, and you could tell your wife/family you are going to take them to Paris for vacation!
Good Luck! Jack
