yeah, at the time. You're talking circ 1989--1993. Vast improvements have been made and really, unless you're doing stupid power, both the 46 series and the 48 series autos hold up okay, iggest weakness if valve bodies but easily upgraded and cheaply. And manuals can be used in a motorhome just fine, depending on WHAT motor home model. And to get max power out of an RB, you're gonna have to upgrade the heads and valve train. especially with a cam. Whether that's stock heads ported and polished or aftermarket aluminum ones, you're still looking at 1000 in heads easy.
