Well,...... took the RV to Utah...towing a 10,000 plus trailer....Awesome tow rig,dropped to 4th gear up the big grades and pulled all of them @ 32-3400 rpms... right around 7 mpg..the 6 speed really works great as the gear drops are right where they need to be when towing... the motor is quiet with the double magna flows and the 3'' tail pipe...the added 2 rv battery's ran the heater all night in the 23 degree weather....the sumo's kept her straight in the wind and passing trucks, and the added trailer brakes stopped her with ease...I never did the 5 star tune yet , but I'm sure it will be a plus to this rig...the power was spot on... but hey, we can always use a little more...right?....for a 22'r .. this has got to be the roomiest little rv ever for me ...sleeps 6... and travels with room for 6 with seat belts...though it was only Sue and I....plenty of room for camping...now the problem....we have the DP Alpine...doesn't get any better...only compromise..SO.... I sold this one...getting picked up today...kinda sad...but there is no way Sue will let go of her Alpine..to go in the Cramper as she calls it.....so BYE BYE little RV... gonna miss you
