I logged 20k miles at 8.3 mph without a towed. Its about 7.6 with 5k miles of a 6k towed. I pull Eisenhower west bound tunnel at 28mph. It is 9% at 11000 ft at the approach to the tunnel. Total weight is about 39,000lbs. I normally run 68mph on the cruise…but I digress.
Unless you start running 50-110k miles a year fuel mileage is a red herring and you focusing on one of least important aspects of Class A ownership. Some B motor powered MH have 5k tow restriction. You will never see 12mph as a long term average. You don't say how much your trailer will weigh. The other concern is every hill you go up you, have to come down. You will need and exhaust or Jake brake, or a transmission retarder.
