with or without a trailer ?


eventually we will be towing a trailer . it will be a 24ft econo hualmark with a dragster in it . so im guessing total trailer weight will be around 5500-6000lbs loaded

We have a 40' with a Cat 350hp motor. With a standard 32' loaded trailer we got 8mpg. With the 32' stacker we get around 5mpg. Both pull great and the stacker actually stops better.

well thats not to shabby !!

i was cuious as i was figuring about 10-14ish with no trailer and taking it easy .

the guy at the dealership said with the genny running full output it would consume about 1 gal an hour .





thanks

MY 6500 ONAN GETS JUST LESS THAN HALF A GAL A HOUR RUNNING TWO A/C UNITS . RUNNING DASH AIR USES 3/4 TO 1 MILE TO GALLON TO RUN . CHEAPER TO RUN GENERATOR AND A/C

ahhh ... this one has a 6500 in it to . also with 2 a/c units . i was figuring less than a gal an hour as i seen other deisel gens run for a long time on just 5 gals {portables} . i think i might have stumped the guy yesterday and just told me a number .

DAMN, all these HUGE Mileage #s from Motorcoaches. I have a 39 foot Excursion with C7 350hp Cat pusher that I travel all year for my business in and tow my 28' hauler behind to race. I get 6 mpg with the hauler and 7-8 tops without it if I drive it easy..

I hear that complaint from a lot of C-7 owners. Mine was the last of the 3126 series with the E designation. I have records of all my fuel purchases. How many miles on yours? I have 137,000+ on mine. Mileage did get better as it broke in.

Hey PMR, did I take that picture of your car or is that a different one?
