We have had our 24' C for 6+ years and 51,000+ trouble free miles from coast to coast and all over the west. I typically tow a 10' {14' overall} cargo trailer hauling either my Indian motorcycle or our Polaris RZR. It is a Ford E-350 with the 6.8L V-10 with a 5 speed Torque Shift trans and a 4:10 rear axle. We have the 55 gallon tank and have averaged 9.5 mpg not towing, 9 towing the bike and 8.5 towing the RZR all while cruising at 60 - 65 {average about 63}.
I do not have any slides, electric steps or levelers and would never own a coach with any of them. Too many problems, too expensive and too heavy all in search of a solution for which there is no known problem {the government does this a lot}.
I carry lots of tools and toys and have not even come close to using all of the available storage. Having the extra space in the trailer helps a lot. We usually run near or even at our GVWR of 11,500 and the ride and handling are excellent.
I agree that having the built in 4KW generator is essential. Used to run a pair of Honda 2,000's when we had our 22' TT and it was such a PITA we often just did without AC.
We used to have a large dog but now it is just my bride and I. While we can easily accommodate a guest or two 99 per cent of the time it is just the two of us. With a great floor plan, 101" wide with 7' of headroom throughout the coach our 24 footer is one of the roomiest out there.
As always... Opinions and YMMV.
