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

We had a 2009 Fleetwood Jamboree 31M 32 ft. Great floor plan. Loved it. Rated for 5,000lb towing. Towed our Jeep great could not even tell it was back there.
My recommended must haves---walk round rear bed. Pantry. NO front window in cabover ( source of water leaks, cold in cold weather, Hot in the summer) No hydraulic levelers ( adds a lot of weight) adequate headroom in cabover. E450 engine. Make sure you can access bathroom, kitchen sink, & fridge when slides are in. Vent fan in bathroom and kitchen. Skip bunk models.
