I tow a 42' Forest River blue ridge fifth wheel with my 6.4L hemi. We travel across country with it. The recommendation I have is add an auxiliary gas tank. No problems pulling even in the mountains. My truck is a 2015 2500 with crew cab short box, 373 gears, 4X4. I added a 46 gallon auxiliary gas tank and can go about 600 miles pulling between stops. A lot better than 150-175 on just regular tank.
Ram6.4Hemi,
Welcome to the forum!
You've provided good information but I'm afraid since the question was asked two years ago the OP has probably already figured it out. :)
