My real world CAT scale numbers.
TV is - 2010, F-150, 4x4, super cab, 3.5 e-boost, 356 hp, towing package. Max cargo is 1411 lbs. towing capacity is 9500 lbs.
TT is - 2010 Dutchmen 25 ft. small slide. Dry weight 5000 lbs. Loaded for the road scale weight 6200 lbs. dry tongue weight 400 lbs. Loaded for the road tongue weight 750 lbs. Hence, dry weight figures mean little.
Cargo - Family, dog and camp gear in truck bed 600 lbs. I am at or near my cargo capacity.
I have towed over 30,000 miles in four years. We have crossed the Rockies twice and spent 6 week circumnavigating the AZ desert.
Plusses - The rig combo works great, no issues with over heating or lack of power. It is small enough to wind through city streets to find shops and attractions. It gets 10 mpg towing at 55 to 60 mph. The TV get 16 mpg around town as a daily driver.
Minuses - The rig combo is maxed out weight wise, so one can assume the appropriate wear and tear on parts. I cannot go to a bigger TT because I am at my max cargo limit for the TV.
Obviously we enjoy the RV life and most of out trip are 3 to 6 weeks long. In addition to the 30,000 towing miles the TV has an additional 50,000 sight seeing and daily driving miles.
I will say the CAT scale numbers were a real eye opener, compared to the weight estimates we all like to make.
Good Luck
