This truck has an added air ride hight adjustable rear suspension. It also has a fuel conversion kit that allows this truck to run on used vegatable oil or diesel, or bio-diesel fuel with a separate 37 gal. tank that is inside the 8ft. bed. If this conversion kit is not desired, I can easily remove it and deduct 500 from the buy it now price, please let me know in advance if this is what you want to do, so I have time to do it. At some point this truck had an after market exhuast system that consisted of stainless steel stacks (like on a 18 wheel tractor trailer), in order to accomplish this installation a hole needed to be cut out in the bed, that hole is now covered by the extra fuel tank that is needed for the use of the used veg. oil is in the bed. Other smaller holes were also made for brackets that hold the components of the used veg. oil convertion kit, and brackets that the custom exhaust used, the exhaust system now does not have a muffler or the tail pipe part of the system. I have posted detailed pictures of all. Please let me know if you need anymore pictures with your email address. You can also contact me at 917-335-6464
