I have a 2004 5.4 with 2.5 inch leveling kit with 33s 3.73 gears I've been getting 7 nog towing a 5000 lb loaded v nose rv with a 700lb wheeler in the bed. Is anyone else getting this mpg usually tow at 65mph

 

That sounds about right. The level and the big tires eat gas.

 

I have the same F150, except with 32's and I get about 14 mpg's without towing anything, so 7 mpg is normal.

 

That's normal. If you didn't have a level and you had stock 31" tires, you'd get slightly better mpgs.

 

That is about average mpg.

Though I was on a bus down to Virginia and we got 6 mpg on a J4500 with only 6 people.

 

sound right to me compare to my 3,55, stock tire, lowered doing 8-9 with my 23' toyhauler

 

I have 33 and wide tires. I get anywhere between 8 - 11 mpg depending on my load. For example, with about 4 adults in the cab and pulling a 18ft center console fiberglass hull boat and trailer, I get around 10 if it's not too windy.

I can average 12 pulling a heavy dual axle iron homemade trailer loaded with 4 wheelers and buggies in the hill country of Texas. Achieved by building speed down hill and coasting up ha ha!

 

I pull a 30 foot Travel trailer, 6000 lbs here in Colorado mountains 7-8 is what I get with stock tires get a little better on the plains can get 9-10 at 65 mph

 

I have towed my 6x12 V-nose tandem axle trailer from here to Arizona several times. I have 2 motorcycles in it, so it's not too heavy. At 65 mph, I get 12-14 mpg at 65mph.

 

I have a 05 with roughly 33" nitto terra, 3.73 and rancho quick lift, edge CTS tow mode. Last thing I towed was about 7k from AZ back to NM and I got 11mpg doing 70-75mph.

 

My truck has 5.4L, 325/60/18s and 3.73 gears. We had a 26' bunkhouse that weighed about 6500-6800 lbs, most of our towing is on 2 lane roads at 60mph with that camper I averaged about 9-9.5 mpg. We up graded to a bigger camper with 2 slides and outdoor kitchen that weighs in right about 7500lbs, 35.5' long and 11'3" tall (almost a foot taller than our old camper), I am down to 8 mpg.
