What should I expect in MPG while towing my RV

[wwest]

2019 Tradesmen 1500 gas with 6000# 26' Airstream I was getting 12-13mpg, and
2022 Longhorn 2500 diesel with 9,000# 30' Airstream I get 14-15mpg. Never go over the speed limit nor do I poke along ...just stay in right lane except to pass. I have to keep reminding myself it is back there.

I just drove Phoenix to Buena Vista, co 700 miles towing a 31ft TT with Ram 2500 4.10 gears

$332 Total - full tank to full tank

4.50 avg mid grade gas - guess

74 gallons

9.4 mpg

I didn't go above 65 mph because the route is hilly in most places and I'm not in a rush.

Temps ranged in the 90 to 70s.

MPG is greately affected by air temp - hot better - and wind.

Use 9mpg for estimating your costs.

I'd guess somewhere between 9-12 depending on how you tow and other factors. My new camper has a more rounded front profile which helps. Obviously speed too. My dad dropped to 55 mph when we towed out west last year when gas prices were through the roof. Even little things like tire pressure help. I like to use cruise control too.

I have 1 2022 2500 long bed 6.4L and get 9-10 when towing a 36' fifth wheel. That's why I got the 50 gallon tank.

I have a 2021 RAM 1500 5.7 V-8 HEMI. I recently purchase a RV Camper to tow with my RAM. I was wondering what sort of gas mileage would I expect to get while towing? The camper dry weight is 5,200lbs. Any ideas and/or recommendations are greatly appreciated!
Thank you!

Keep it under 70mph and you will get 13, go over it will drop fast yo 9 or so. Use tow/haul setting.

Funny how so many people have an opinion about this question, and without asking enough information about your truck...
First...
Trailer weighs 5,200 lbs. - What kind of RV Trailer?
5th Wheel? Travel Trailer? How Big / Length?
Engine is a 5.7L - and assuming an 8 speed transmission...
What size Rims & Tires?
What rear end gear ratio? (3.55 or 3.92)

I have pulled a 27 ft 9,000 lb 5th wheel for 6 years with a 1500 / 5.7L / 8 speed/ 3.92 gear for both short and long trips... I typically average 12 - 14 miles / gal depending on road speed and amount of hills to climb...

I recently towed a 28' 5,500 lb Travel trailer to Canada and back to Arizona. On the way there I was keeping up with the speed limits and got 5-8mpg. I checked with a performance shop in Canada to see if there was anything I could do to improve my mileage and the guy told me to stop driving with the speedometer and use the Tach instead. Apparently 5.7L Hemi's run optimally between 1500 and 2000 rpm. I drove using the Tach back to AZ. and got 9-13 mpg. Sometimes I was just maintaining the minimum speed limit, but the mpg difference was a fair payoff. My next step is to install and air diffuser to kick the airflow up and over the trailer to see if this adds 2-3 mpg. Stay tuned!
