I’ve pulled 2 campers (had airstream now ORV) well over 100k miles over the last 15 years. If your truck is Tate’s Weight doesn't matter that much. Last summer I moved my buddies 17’ 3800 lb camper 400 miles and I see the same MPG pulling my 6800 lb 22BHS. Aero drag matters more then weight. My current tow rig is a LX570. I get ~16mpg on the highway, towing my camper at 55-60 mph I get 9 mph, 65-70 mph I get 7.5-8mpg, at 75 mph I get 7 mpg (so 25% less then 55-60). I’ve done some estimates of what to expect based on my towing up to 10k miles a year. Pulling my ORV 22BHS I’m estimating 50% range running 55-60 mph and 60-70% reduction running 70 mph.
also I noticed almost no difference in mpg from my Airstream I had for 9 years to my ORV we’ve had for almost 6 years. Also Both campers were almost the same size and weight.
