I’d get exactly 17” travel with shocks through the bed where it’s bumped currently.I did the same with the bed as Turbo but went a little further up. I trimmed about 2 inches out fo the factory bump stop area bracket. I run 18 inch bypasses through the bed with a Shifter boot acting as a dust shield to keep interior nice.
I get about 17 strapped and bumped out
Bumps stick into the passenger compartment by 1.5”, but it’ll still be comfortable to sleep in there with a mattress.
If you bail the e-brake and inner fenderwells and bump the axle all the way to the frame, 19-20” travel is achievable.
