Where to purchase truck & FW?

I think that you should do an online search regarding taxes and types of units available. You stated that 2 families are involved. So depending upon your numbers, are we talking about one or two units? If 6 or more are involved, you fiver is out of the running, as you now need 2 trucks. Having people ride in the FW while in tow is a BAD idea, and in many states illegal. A TT type trailer pulled by a Suburban would be ideal if you have more than 6 in your party. As stated, some states have a much higher taxing rate on everything from food, gas, and yes vehicles. Doing a pre flight search could result in many $$$ savings. And remember, what you purchase, you will probable have to sell prior to your return home. So buying a NEW unit might not be your best bet, as you probably will take a big $$$ hit the first few years of ownership on anything new. Purchasing a tow vehicle for the FW is also tricky. You want a truck large enough to properly tow or haul your unit safely. I still think that a proper TT will fit your needs, and with the proper tow vehicle It all depends upon your 2 family numbers. We on occasion have encountered as many a 10 people traveling, camping, in a bus conversion unit. Enjoy your stay in the USA.
