I am considering getting a small enclosed utility trailer, 5x8 or 6x10 or so with average load. Anyone out there have experience towing something like this know what impact it will have on my fuel economy? I will be putting about 5k miles on it this summer so I'd like to know.

My 14' open quad trailer when loaded is about 2500 lbs. I get anywhere from 9-12 mpg when towing. Of course this depends on grade of road and speed of vehicle. I drive fast, and am typically driving in mountainous areas.

I occassionally tow a 4x8 1000 lb trailer and it brings me from around 20.4 mpg to around 18 - 19. Not a big difference.

normal mpg - 17.75
w/2,000lb camnper mpg - 16, and that was over the divide on I-70.

always amazed at the range of fuel economy when these topics start.

When towing my old pop-up and 33" Boggers on the truck I got about 12 mpg (about 2 mpg less than without the camper). Towing a 5x10 u-haul (2 axles) with about 1000 lbs of gear and 33" swampers I got about 13 mpg. With my 4,300 lb camper, my wife and two kids I averaged about 9 mpg with 31" MTs. This was pretty flat ground, from south eastern GA to Houston, TX. Best tank was about 10.5 mpg, worst was about 7 mpg (I was trying to get home and was doing about 70 mph, from my usual 60 mph). Without the camper and 31s (and the family), I get about 17.8 mpg with the AC on at 75 mph.
