I am taking my 98' 2500 down to fl. towing a 35' 5500lb camper trailer. rear hitch not 5th wheel. The trailer is cherry with new bearings last year. (see signature for mods) I am wanting to know what kind of mpg I am going to be expecting on the highway. I cant get good estimates because mass and nh have lots of hills that mess with readings. My trip will be all interstate mostly flat. to orlando. From mass to fl. anyone here make that trip? I am getting 22 on highway now empty without leadfootitis. any help would be appreciated.

12 to 16 would be a fair guess

You should get in the area rich said. I get between 21 and 22 driving locally and get around 15 towing my 30ft 5er that weighs in at around 11k and I am sure that it has a much higher front than your bumper pull so you might get a little better.

thegoat86

yeah, I was hoping for around that, I dont like going over 65. I was getting 13, 14 when I headed into the mountains around nh. thanks.

Don't know about your mileage. But here a traffic tip when u get to florida.Take 295 south to bypass jax.TONS of road construction on 95 south around jax area.

thegoat86

Thanks, I dont think they will ever finish that stretch. it has been under construction for almost seven years now.

13 to 15 with mine (back roads versus Interstate; non-mountainous terrain)

WestTN

I have pulled my 29' conventional TT to Florida several times.
My fuel mileage is 15mpg at 55 mph,
13.9 at 62 mph,
12.4 at 70 mph,
11.3 at 72-74 mph.

Don't worry about the towed weight near as much as the speed.

Starting at about 40 mph, the wind resistance increases with the square of speed increase.

i'll put my money on 8.5.

I had the same results as WestTN with a '98 12v 5spd

How does a 35' trailer weigh 5500? Most 35' RV's weigh at least 12k.
I guess your truck is set up to deal with the wight, id indeed it weighs that much?

nkennedy

That was my question too. How does a 35ft TT weigh in at 5500lbs. I had a 29ft that weighed 8K lbs. I have a 32ft fifth wheel that weighs 11.7K lbs. I usually get 11.x MPG towing in the flats @ 62 MPH.

Expect around 11-12, but don't cry if it's only around 10 if you go 70.
I take a 5 gal can of fuel, for when I am trying to make that last few miles to the truck stop, driving from southern Oregon to Alabama.

St Auguustine, FL, resident here. On the I-95 situation in the JAX area: once you get to I-95 just past the airport, take the 9A bypass. It is a good, new road with no construction. It is much shorter and less congested than I-295 around the west side of the city. Safe travels. PCM

I have averaged on long trips like to Newfoundland or Alaska 12.7 running 60 to 65. 4.10 rear end, six speed towing a 16,000# fiver. I am always within .2 of the 12.7 number and have calculated two of the long trips manually to check out the computer numbers.
