I am selling my Lance camper and going to a 20 ft bumper pull that weighs about 4400 lbs. dry. What is a reasonable expectation for fuel economy when towing. I typically get 20 plus hand calculated on the highway keeping rpm's 2000 or under.

 

I don't have a camper but a 14K fifth wheel and I average 11-12 mpg. You are a lot less weight so I imagine you will see at least 13-14 or better. I do have a programmer that I use and an AFE intake.

 

I got about 12 with an 03 SRW towing a 30' mid-height 5th wheel. I might get 10 with my current 40' with 06 dually. It's also significantly taller.

Speed seems to have a massive impact on towing mpg.

 

Ditto what these guys are saying, except when I'm towing in the hills of AZ.. I drop into single digits pretty quick..

but flat towing I'm in the 11mpg range. 12k 5th Wheel.

My older trailer was lower profile and only weighed about 7k, I was getting 13-14mpg.

 

7K 18' open car trailer loaded 13 MPG @65-70
10K 28' enclosed race trailer loaded 11 MPG @65

 

12.5 - 13.5 with enclosed cargo trailer @ 65 mph or slower. Above 65 drops off fast. Does not matter the weight (empty, 1 or 2 bikes, or furniture being moved), it is the wind resistance. Took it to Sturgis last year from Florida and averaged 12.5 with lows of 10.5 towing 75-80 and highs of 13.8 towing 62 mph. Tried different speeds with each tank to see what effect mph had on MPG. 2 bikes and camping gear with 4 people in cab.

Travel trailer @ 9,400lbs which is taller than cargo trailer - 11.5 - 12.5 @ 65 and under and MPG drops faster than with cargo trailer going faster than 65.

 

+1 but if I keep it at 55 I get 15 mpg in trips from CA to UT. Lots of mountains.

 

speed is a mpg killer for sure....

 

Seems like the second I plug in to a trailer and hit the two-haul button my mileage drops to 10-12 on all three of my CTD trucks regardless of weight. Seems like frontal area drives it. Head winds will knock it down below 10mpg if you're so unlucky. I tow at the speed limit to keep up with traffic flow, except now in UT we can go 80 in many places but I don't usually go over 75.

 

9 mpg at 68mph in California. AC on and 10K toybox.

 

Last time I pulled my trailer I was hauling a John Deere 4440 and with my g56 if I kept it under 60 I was getting 15 mpgs but as soon as I went over that it dropped to around 10-11

 

I used to drive a 4440. You had to have quite a bit of weight.

 

I have an '08 Keystone Energy that weighs in around 6k dry/10k wet and max loaded. I've gotten low teens when it's dry, and 9 to 12 MPG between 55 and 60 MPH when loaded. Head winds are also a killer on MPG.

When I was getting 20's and towing a trailer of similar size/weight it was about 12.5.

I'll echo speed and the resulting wind resistance is a greater factor than weight. At 55 I'd get 13.5-14 mpg. 12-12.5 at 60-65 mph.

 

I just took a trip to Indiana from N. GA going up through the mountains up to Nashville I got 11.6 pulling my 5er (14K) the second tank the road flattened out some I got 11.8. All of the driving was around 55mph on the 2 lane and 65mph on the interstates.
