Jacking Options for Frame-Laying Trucks

[epon]

Wondering what folks do when they need to jack up the truck on the road for a tire change due to a flat. I need to drive up on blocks to get a floor jack under the frame and I suppose that could be done on the road as well but cant easily be carried. I've seen the 4x4 bags that are filled with exhaust, or maybe a stubby bottle jack and a jack stand behind the seat.

I'm also curious if people have designed in a way to get a bagged truck that lays frame on a flat bed that has suffered an air system failure. The most graceful solution I can muster is a hidden hitch on the rear behind the license plate and the front something borrowed from the race car world and a hold in the bumper for a screw in hook eyelet. Hope to never need it but would be pretty happy it was there if I did.

TIA
