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 ...
Get the 24 for sure. Outside, about the same as a big truck/truck camper. Inside, much more space, comfort and storage.
The longer C's are boat anchors. Parking for day trips can be difficult. If you end up with a toad, you are really long. The 24 is a lot more maneuverable and easier to park.
Here's a photo of our 24-1/2 Minnie on the square in Downtown Arcata. Try that in a 29 footer.
