Class C regrets/Options you wish you had?First time class C

The only things I don't have and wish for are a walk-around bed and an inverter to prevent having to run the generator to work on the computer on the road. Also I wish for better storage, like on a boat, but apparently that just doesn't exist in the RV world. If I were going to full-time, I'd be tempted to tear it all out and build decent storage.
