We started full timing last year but not traveling to much. We did make a 2 week trip to KC(about 3,000 mile trip). we learned a lot about towing our 2850BH.in the flat lands I filled all the tanks(ballast). when we were in Ozarks I would run with them empty. this seems to work. My question is does the fifth wheel set up pull better in the wind? is it worth the larger investment? We will go on the road full time in about 2 years.
