Weight vs gas mileage?
I'm sure this question has been asked many times but I did a search and didn't find much. Looking at small TT the weight difference between 18-19 ft TT's and 21-22 ft TT's is about 800 lbs. 2600 vs...

A 10,000-pound increase in GVW or GCW will increase fuel consumption by about 8.5% (0.55 MPG) and is
equivalent to a loss of 80 engine horsepower at 45 MPH (8 HP / 1,000 lb @ 45 MPH) on a 6% grade.
Some facts to consider:
• Proper tire inflation pressure is important for your safety and that of others. Maintaining correct
inflation pressure based on the actual tire load will also optimize tire life, vehicle ride quality, and fuel
economy. With a tire pressure 10 psi lower than the manufacturer’s recommendation for the weight,
fuel economy will drop 0.5%.
• All tires are least fuel-efficient when new. As the new tire wears, the rolling resistance decreases
and fuel economy improves.
• Most of the fuel economy advantage is obtained when the tread is 50% worn.
• Regular radial tires and fuel economy labeled
