Boy, if that were true, my truck would be riding on the bump stops every time I hook up my 5th wheel.....not even close to being an accurate statement!

Do us a favor, go take a picture of your front bump stops then (the space between them and axle)......we'll see just how inaccurate my statement is.

Even though the OP has a SRW, and yours appears to be a 450, still interested in your findings.

OP, your best bet is to go with an adjustable suspension system with airbags. My wife's Grand Cherokee has four corner suspension and can lower itself 3 or 4 inches to make getting in and out much easier. If you wanted to go super low, you would have to notch the front and rear frame rails and hope there are no interference issues in the front suspension with the track bar, steering, and sway bar. The rear suspension would have to be converted to a link system like the Kelderman setup since leaf springs will likely only go so low before their spring rate overcomes cargo weight and stops.

Another option would be Liquid Springs, but that is a pretty pricy setup, and you will still probably have to go to a link style rear suspension.

I've seen vans with ramps that come out of the side of the door, could something like that not be done here? Maybe that along with lowering the truck as much as possible without extensive upgrades under the truck would get the OP where he needs to be?

I believe he is right, my front suspension on a 4wd stock has very few inches between the bump stop and the perch on the axle. The bump stop may allow some compression on very sharp impact but it won't give much on a static load if something like an air suspension system lets air out to lower the whole truck

The amount of travel on the rear is less relevant since the driver's seat is right behind the front axle and that's where the lowering matters.
