When not towing the TT I'm towing the boat. Being from FL I leave the boat hitched and use the back as a boat locker for toys and gear. When it's time for a trip I pull out the boat stuff and load up the camping stuff including bikes and vespers. The kayaks are on the roof most of the time. Plus, I sometimes trade our the cargo for family and fronds. We've had some awesome adventures and experience!
Back to questions.... Around town I'm getting 17mpg. Towing the boat about 12. Towing the camper about 6.5. Is it all weight and wind resistance? Am I driving too fast maintaining 68 - 75 mph? I'm planning 6000 miles starting next month going over the Colorado Rockies twice!
Thanks for your replies and help!
