I just bought a 24’ class C with dinette slide. It’s the perfect size for 2 of us and very easy to drive and maneuver as well as a good towing capacity. (7500 lbs)
A slide will give you more room when parked but sometimes much less when it’s in.
For just 1 person and dogs, a non slide would be fine without any worry of issues of it not working.
If you want to stay on the shorter side, I narrowed my choices down to the Winnebago 22R, Forest River Sunseeker 2290 and Fleetwood Tioga 25K.
I decided on the Sunseeker and love it. Even with the slide in there is plenty of room to move around. It also has large tank capacities and you can’t beat the Ford V10 and 6. Speed transmission.
Good luck.
