OK had to post and rant (kind of). I delivered and engine to a friend in Kansas city this weekend from Central Il, about a 900 mile round trip. This is the first time in a few years that I have had my pickup out on the road for any length of time so I decided to check my mileage on the way back to Illinois yesterday. The truck was unloaded except for two adults and less than 50 ibs of luggage. All interstate driving with the cruise set at 72 with the A/C on. The truck is a 99 Ram 1500 Quad cab Sport 2WD with the 5.2 and an automatic, 3.55 gears and factory sized tires. The normal stuff that kills mileage is good - the truck has 80,000 miles on it, plugs and wires have 25K on them, air filter - 4K, Mobil One 10W30 in the pan, all tires checked at 40 psi hot. my best mpg was 15.8.....is this normal? I was hoping for at least 17! any thoughts or suggestions

Try 62 MPH instead of 72 without the A/C and you should see a HUGE improvement.

It's a truck.....anything over about 65 MPH (105kph up here) is going to kill mileage. Even my 92 Cummins diesel looses about 4 MPG if I drive it at 65 MPH instead 0f 60MPH. I wouldn't turn off the A/C as such, but if you slow that puppy down to under 65, I bet you'll get at least 17. Everyone in my family has a truck...different years and different engines, and they all react the same to the difference in speed.
Also....16MPG down there is like 19 MPG up here in Canada.....I'd say not too shabby for a pickup even at that.

My 96 4x4, stock except a high flow cat got 15mpgs mixed. Not much highway as in non stop driving. In a 95 2wd I averaged 13mpg towing a trailer both ways and 6k pounds loaded on the way back from Pitt to Detroit. Although I didn't really drive over 60mph with it loaded.

WTF is a "tunnel cover" and which tunnel are you covering ?!?!? I'm looking in the Canadian Tire catalog and I can't find a "tunnel cover" !!! I'm gonna try Google next ...
Tonneau cover maybe ?
And wow...sure sounds like kinda bad mileage? (Chevy truck owner, so haven't had a Dodge to compare with)

I just managed a best of 21 MPG's with my 2001 Dodge Ram quad cab shortbox SLT 2wd with a 5.9L Magnum. grnated my truck has a bit of work into it to make it more efficient, but 2wd 5.2L's should easily get 17-20 MPG's in nearly stock form (highway, of course)
