agree - his setup is not 'set-up'
bags are probably rated at 5000 lbs (depending on the set he got)
and if setting his at max psi doesn't lift it,
then he either has more pin wgt than he guesses 3500+ pin + 1000 bed + ????lb 'Stuff in the trunk' +......?
OR he has an issue with the bags - broken or only 1000 lb bags ?
let us know what you find please !
