I am a travel trailer guy who has tried the fifth wheel thing, but highly recommend a motorhome if traveling is your thing more than squatting in one place for weeks or months at a time. The towed vehicle can be an off road model or one that gets great mileage. Playing tourist is a lot easier in a small vehicle. Another example is that I don't drop my trailer at Walmart while exploring an area, but it is easy to park the motorhome and drive off in a toad.
If you are going to sit in one place for long periods of time, nothing provides more bang for the buck than a travel trailer.
