93 Chevy 4x4 dually crew cab, 454 gas guzzling machine. Pulling my 28' tag over the mountains to Denver, it gets 5 mpg on a good day @ 30 mph. The continental divide is a real pain!!

2001 International 9900 pulling a 51' Pace Gooseneck.
850 ft-lb of torque, passes running 80 mph like there isn't a trailer behind you.

2000-Fleetwood Discovery Diesel pusher 37 ft. Real comfortable.

1984 chevy 2-wheel drive crew cab dualley with a desial out of a bus with a 2 ton dump truck 4-speed trans and a us gearvender aux over/under trans behind that..no stopping this thing.if you can hook on to it then it will pull it and not know it's back there.

I have had two mid 80's dually crewcabs with 454 5mpg tops, and we have mountains out west, I hope I never pull with gas again, I love my duramax

Hopefully next year.....

97 Georgie Boy 34 foot class a motorhome with 454... It has the banks power pack (yes banks makes gas stuff too) and gets 10 mpg pulling my 28 foot trailer... Once you have a motor home you wont ever goto the track without one!

2006 Dodge 3500 with cummins. Love it.

'03 Chevy Crew Cab 6.6 Dura Max, Allison auto. Pulling a 32' tag gets 12-14 mpg. No complaints.
