Which is the better way to go 5th wheel or motorhome?

It all boils down to one truth. How do you travel? Parking for extended periods of time? Fifth wheel. Move ever couple of days? Motor home. Everything else is superficial. Motor home will get worse fuel economy and cost way more to buy and maintain. Diesel trucks, especially new ones are returning really good non towing fuel economy numbers. Most of us really pay no attention to fuel costs. In the grand scheme of things that is one of the smallest cost factors.
