Thy safest bet would be to look for a small toterhome, some are expensive, but you can find older models that are not too bad money wise. The older models will not be a speed demon, but you will have big truck brakes, tires, axles, and of course plenty of towing capacity. My old toter was a 16 foot box renegade with a slide out. It was enough room for my wife and twin boys for about a 4 day or so trip. My boys got older and we upgraded to a motorhome version. Here is the old toter with a 40 foot gooseneck.
