    I am in need of a maintenance trailer. Mabey a 14ft Enclosed. Just curious how much worse mpg you get vs an open 14ft?

    I'm trying to have a more efficient setup. I ditches my trucks fancy mud tires at 12mpg and put on stock size muds for 17. I plan on buying a flatbed trailer for heavy hauling. Wasn't sure about an enclosed killing my gas milage. It would be a moving billboard.
    Someone list your normal and towing your enclosed. Along with trailer dimensions.

    I tow a 8.5' x 24' enclosed trailer (Haulmark Thrifty Hauler) loaded to around an estimated 5500-6000lbs total for my normal roll out. This is attached to my 2006 F350 6.0 PSD CCLB. Here are my AVERAGE numbers from the lie-o-meter in the dash (its usually .5 to 1 mpg in the optimistic range). City is a small rural city here, not stop and go traffic.

    Unladen Driving Highway: 18MPG
    Unladen Driving Mixed 'City': 13MPG
    Towing Above Trailer Highway: 11-12MPG depending on speed
    Towing Above Trailer Mixed 'City': 8-9MPG depending on how many accounts I stop at

    I've found that anything above 55MPH brings the mileage down substantially, obviously due to having to overcome more wind resistance. The ultimate MPG hit you take is directly tied to how heavy your right foot is. Some guys say they can pull the same size trailer and get better mileage, but they get beat off the line by semis normally. I tend to tow like an old lady normally drives, just so I don't piss the people off behind me TOO badly.

    My 7x16 10,000GVWR open trailer doesn't do too much better, I normally saw 10 or 11 MPG in the city situation - never any highway. The enclosed is worth the hit in MPGs though - you get a rolling billboard for your business, and your "Oh crap is someone stealing something off my trailer?" thoughts quiet down when you're in a backyard and can't watch your trailer. ;)

    These types of threads always turn into a pissing match and a liefest on other forums though, so be prepared to see some crazy numbers being posted! :laugh: I have no reason to lie, I am just going by the in dash computer numbers - if anything they are consistently wrong, so it gives you a rough idea.

    You are right, the enclosed trailer is worth it for a lot of reasons. I would never want to go back to an open. We may get a box truck later, only because we don't want our guys pulling a trailer.

    I probably get like 13-14 mpg towing down the road but I have a v nose and a diesel which helps.

    i currently have a 16 foot v nose trailer that replaced a 16 foot open trailer and the gas mileage is exactly the same. even towing a 14 foot dump the mileage never seems to change. I get 195 miles per tank like clock work on a 2002 chevy 6.0 gas hog.......
