We are looking for a 23 or 24 feet class C to replace our truck camper Good floor plans are rare in that range we see more in the 28 to 30feet We like the easyness of our TC and we think 30" is not ...
We just looke at a 24 foot Class C Prism, lovely rig but we do a lot of sightseeing and use all sorts of campgrounds from disbursed BLM to RV Resorts and almost as many miles sightseeing as traveling. For us making and breaking camp everyday wouldn't work.
26 to 28 seems best for us, 28 seems to have dinette and sofa and we like that. We also tow a Sidekick for sightseeing. You gotta find what works for you. Rental agencies can be of help.
