We have a 24ft class c, a 2005 Fleetwood Tioga 23e, on the Ford E 450 chassis. We are thinking of getting a 4wd conversion done by Advanced Four Drive in Salt Lake City. It would make driving on some of the dirt Forest Service and BLM roads near us a little more do able if it rains or snows because of the 4wd option and the extra ground clearance the conversion offers. Also more practical to drive over the Sierra passes near us in the winter. We would NOT use it for any off roading. For any of you that have had a 4wd conversion done to a class c, how did it impact highway driving or road manners? Thanks!

I suggest going over the SportsMobile Forums and doing a search. This topic has been covered a lot, and there's a few folks who where not happy with Advanced. I would be especially wary on a motorhome, because they tend to not use robust axle options, and may not have enough suspension travel to tame the ride. They also machine their own brake rotors and/or hubs, so brake jobs can be difficult when it comes to sourcing new parts.OTOH, I highly recommend QuadVan. It's all new OEM Ford parts, which makes it ride well, turn sharper, and is easily serviceable at Ford dealers. I'm using them for my van, and will be going with an F550/wide-track axle to get the tightest turning radius possible. Their standard axle brings the turning radius in 7-ft, and the wide-track even more.

Caringb, Thanks for the response. I have read many of the forum posts about Advanced as well as Quadvan. Seems to be some split opinions there. Advanced uses a leaf spring suspension and Quadvan uses (I think) coil springs. Any pros and cons for a heavy duty vehicle such as an rv on the E450 chassis?

Would not a selectable locker in the rear be a worthwhile option?

how much does a conversion of that kind cost these days?

A basic 4wd conversion at Advanced for a class c motor home is $12K. I think Quadvan charges more.
