Philisophical question about a jack
I have a 2" receiver in the rear. I have a 2" receiver in the front. Why don't I have a jack that would set into a 2" receiver to raise the truck?

LOL !!!! Not a bad idea other then you are lifting the entire end of the truck and one it would be very heavy for us with a diesel engine. It might be a bit wobbly also if your on an uneven surface. I lke it for the read though.

I have used my hi-lift on the rear. You have to jack a loooong ways up - until both shocks are topped out - before wheel leaves the ground. A hydraulic jack under one end of axle requires a whole lot less lifting and is much more stable.

There are two reasons I wouldn't do it.
One, a jack under the axle near the wheel retains the stability of 4 points of contact on the ground. Jacking the entire front or rear from the receiver leaves you with only three points of contact on the ground, with a pivot point in the center. I'd think this wouldn't be very stable.
Two, I don't know about your truck but the front axle of mine carries well over 4000 pounds. My front receiver hitch is rated for a line pull of 9000 pounds, and a vertical weight of only 500 pounds. I don't want to try to lift the front of the truck with it.

The rear receiver is rated for 2500 pounds, and the rear of the truck weighs a lot less than the front.

good idea but a little to close to a bumper jack for me
My hilift does have it's place but I never use it for service or repair work....unless I am trying to straighten something out.

We used to have pneumatic onboard jacks on the Trophy Truck but with 34" of rear wheel travel you had to strap the axle with some special limiting straps before you activated the onboard jack; very slow.
We now use aluminum floor jacks if we have to change a tire on the fly.
The 'jackstands' we use on the rear of the Trophy Truck (when we need the suspension at full droop) are more than 4 feet tall and hook into the (much battered) rear bumper.
We jack the rear of the truck up via the center section during pitstops but nobody, I mean nobody gets any part of them under that truck when its on the jack.
