87 3/4 ton LWB lowering questions and advise

[Dingman]

Trying to get the rear down a bit. What should I use? Would the shackles be enough? I still need the truck to tow a 27' trailer.

I also would like the wheels and tires to fill in the fenders better.

Succestions on Wheel and tire size? I would like to go to a 18' wheel, But the Tire size I am having a hard time with.

There are some great long bed trucks I have seen with about what I am looking for.

I am still trying to get some pics of My daughters truck posted on here.

Thanks for the site guys. I love the information.
