getting IN and OUT of vehicals with 5ft of lift.
A guy I work with has either a F250 or F350, on 44's now, and what has to be 20" of lift on top of that (over exageration, but its freaking huge). He's 5'10"ish. All he does is climb the front tire to get in. The bottom of the cab is damn near at his shoulders. I'll have to get some pics some time. Its like watching monkey climb a tree watching him get in.
I dont think you'd have to worry about the truck or anything in it getting stolen. I parked next to a f350 one time at school, and it was tall, specially when parked next to mine. The front bumper on his was right around the height of the top of my bed.





Maybe one climbs on the others back then the other one lifts him up...
