I have a pretty much virgin 85 pickup long bed with straight axel front. I'm thinking of running 33X10.50 BF MT's. Can anyone tell me how much lift I need to clear? I was thinking of a 15x8 rim with 3.75 back space, I think 4" is standard.
I don't want to go higher than needed so it's still good for the roadway. I plan to use it as a tow vehicle for the motorhome, but want to have enough clearence not to be turned around when encountering deep ruts etc.

Thanks for any experiences you can pass on.
