So many trucks and suvs with lifts. Wouldn't this have an adverse effect on towing and mileage efficiency?

Should one stay away from purchasing a jacked up tow vehicle, i.e., Excursion, F250, F150, Ram, GMC, Chevy etc?
Their is nothing wrong with a lifted vehicle as long as you are within reason. 20" lift and 44 inch tire is not a good idea but if you are talking about 5 or 6 inches lift and 35 inch tires it would do fine and be safe. I used to do custom 4x4 builds and have used many of them to tow with. They are as safe as any other vehicle if done correctly. The aftermarket suspension kits are DESIGNED BY ENGINEERS AND ARE SAFE. I would rather tow with one of those than some of these pulling combination that are being HIGHLY recomended on here.You are definitly going to loose power and gas milage unless you regear the frt and rear differentials. YOU WILL HAVE TO REGEAR. Putting chips and performance parts on to try to compensate is still going to leave you lacking pulling power and bad gas milage. Still don.t buy into this stiff TV stuff beating the rivits out of the trailers because your trailer is independent of the TV and has it's own suspension but you will have to have a drop hitch and possibly a custom made one depending on how high you vehicle is lifted.

When ALL the steel spring suspension parts were replaced by Kelderman installing their level ride air bag suspension with air compressor and 3 gallon air storage tank, the rear springs were replaced with two 5,000 pound rated Firestone air bags. Thus I have a 10,000 "spring" suspension capability on the rear, but the axle is still rated 6,010 pounds and the two stock Michelin LT 225/75R16E tires are rated 6,010 pounds at 70 psi. The front air bags have a slightly higher rating than the front springs, but that axle is rated 5,500 pounds. They also installed new shocks on the front and re-used the OEM shocks on the rear. Fifth gear is the towing gear for 55 to 65 mph.

While the door tag suggests a GVW of 9,600 pounds, the axle and tire ratings could support 11,510 pounds GVW. The 27FB Classic has a GVW of 9,000 pounds. So the door label combined GVW of 20,000 pounds would mean the truck could be supporting up to 11,000 pounds with the fully loaded trailer in tow.

There is a switch in the console that can be turned on to energize the rear air bags air dump valve and lowers the back of the truck to the stops in the air bag. As a short person, I can now easily load stuff into the truck bed. Turning the dump switch off, the bed rises back to level.

The ride was softer after leaving the Kelderman shop in Oskalosa, IA than when I arrived from Indianapolis,IN.

The Hensley hitch required the two inch drop to have a level trailer (a two inch square bar welded to the bottom of the two inch square one sticking out of the truck receiver.
