I have a 2006 PW Lexor TD on a chev- the lexor uses the chev body- so we are narrower.
I was under my van today- there are a couple of scrape marks here and there, but I also admired the makeshift looking guard for the drain on the fresh water tank. Everything looks like it is made so as not to snag.
Like yours, my grey water comes all the way over from the other side, but no problems, the heat shielding wrap ( it runs close to the chev exhaust) is a little roughed up but that's about it
I really don;t worry about clearance and we have been on some dirt and gravel roads with washouts, pot holes and rocks.
you can ensure that your suspension is correct whether airbags or shocks.
when coming out of a driveway, go straight out then turn once you are level.
enjoy! I love our PW we bought it at just over 80K, and are close to 100k now.
