Heavy towing numbers?

[GPD270]

What are some or your mpg's when towing heavy.

I towed my 14k 5th wheel to Fla. and back and got around 8.2 at 66mph. The Cat Scale said I was right at 25k loaded. My truck has the 4.10s. Just curious to see what some of you were getting. I did a search on this but got the phone book. Truck is stock at around 1200 miles on her.

I tow a 15K 5er and I was seeing around 10 out of mine running 60-62mph. My truck was an 08 cc/sb with a 6 speed.

Was that with the mods that you have in your sig?

No, it wasn't! I drive a 2010 350 now. Those numbers were on my stock 08.

Not a problem! I haven't had the chance to tow with the new truck yet. Hopefully with all the mods on it, it will see better numbers!

only 1200 miles on the clock? your mileage will come up some once the engine breaks in more. my father in law tows a 32' 5er toyhauler and it getting almost 12 loaded.


its a 08 F350 SC/LB SRW auto 4x4 with 3.73 gears

If you do please shoot me a PM on what you get. I dont mind spending the $$ on mods if I see a good result. My 5th wheel weighs in at 14.5k unloaded so it seems our weights are in the same ball park.

Yeah I was thinking about that too. I figured at around between 5-10k miles it would improve some.

They sure do! What type do you haul? I have a Carriage compass. 38' with 4 slides. Last time I had it on the scale, it was 17K fully loaded with clothes, water and all the necessary stuff needed for the wife and kids...
