Definitely the Safari DP, although I just might be a bit biased. Went through the very same comparison 4 years as you are now (neighbor had a class c for sale & then we saw the Safari). First off, the suspension, it's called a Velvet Ride, a torsion bar like system. Mine had a bit of a harsh ride and wanted to wander a bit. Went to the New Koni's and new Toyo's and it rides like a dream. Just an FYI, the price of tires bacame scarey, replaced all 6 last December at $2,800, mounted balanced, and siped. I have replaced all three TV's with flat screened LED's but that was more because of the HDTV change. The other upgrade that was very helpful was getting rid of the Halogen lights and converting to LED's. If you want to get the Straight Skinney on all Things Safari, there are two different Safari Coach Yahoo websites. Especially the straight skinney on suspension system adjustments (via shims), cheaper than airbag replacements. Those websites have all the "Documentation" you will need that can be downloaded. In their Files Section look for and download the Used DP Motorhome Checklist, it is one of the best for checking out most all DP's. We used it in rejecting over 7 different coaches.
