When I brought the 2013 25FB International Serenity home to the Phoenix area from the selling dealership in Los Angles towing with my 2007 Mercedes ML320 CDI diesel, the Hensley hitch kept the sway towing issues at bay on I-10 in Arizona with lots of semi trucks passing at 80 while I was at 55 mph. Unfortunately, after the load out for camping, the CAT scales reported overload conditions on the front axle and the GVW was exceeded.
I made the migration to a 2012 Dodge Ram 2500HD diesel and, to borrow a USPS motto, if it fits, it goes.
I balked at acquiring the last official 34' Classic (#25 of 25) as the 11,500 GVW could have put me in a very overloaded condition when looking at the GCVW numbers.
Our 2014 31' Classic is the perfect match for us with this truck.
Absolutely no issues towing in the mountains even at the CATR scale weight of 19,200 pounds. The engine brake gets good work out on steep declines and the regular brakes are seldom touched. I get the usual 12 to 13 mpg on the flats and perhaps 10 going up steep inclines at whatever speed is needed.
I think the 10,000 pound GVW of the 31' Classics need a ¾ ton truck. The Flying Cloud & International 30/31' models with a GVW of 8,800 pounds are strong candidates for that size tow vehicle as well.
The issue is the real payload of the tow vehicle versus how much stuff we take plus the typical over 1,000 pounds of tongue weight to be carried.
