I might add to my post above regarding our 11'5" tall Itasca. We wanted the flexibility of having a Class C that was optimum for comfortable camping in the largest possible variety of situations. As a result of it's great overall storage capacity inside and out, we keep it loaded about the same way all the time regardless of what kind of trip and camping we are planning on at any given time.
Here's some of the items we have nearly always loaded in it - with no items other than hanging clothes and shampoo in the shower, and no items hanging off the outside (the spare is even mounted up underneath in the rear just like in a pickup truck):
- several fishing poles
- full size beach umbrella
- full size shovel
- full size broom
- 120V air compressor
- portable generator as backup to the built-in generator
- full size portable propane fire pit
- 5 gallon propane tank for the fire pit
- 2 gallon propane tank for the fire pit
- full size outside table
- 2 full size outside lounge chairs
- 3 regular outside chairs
- 2 side tables for the lounge chairs
- tire chains and tire changing eqiupment, including a full size inflated spare and a 12 ton high lift hydraulic jack
- 2 gallon gasoline tank for the portable generator
- spare 20 foot sewer hose, plus the regular 20 foot sewer hose along with a 5 foot extension for it
- 100 feet of fresh water hose
- 50 foot 20 amp shore power extension cord, with an adapter to able to add it to the regular 30 foot 30 amp shore cord
- extra fluids for the V10 engine and both generators
- outside BBQ grill with propane bottles for it
- outside single burner propane stove
- 5 3-step leveling blocks, plus additional pieces of leveling boards
- an array of rockhounding equipment
- outside carpet
- a tarp
- at least one to two weeks supply of food
- rolled up insulation for all coach windows in case of severe cold temperatures
- several blankets
- cold and warm weather clothing
- portable 12V high volume multi-speed fan with extension cord for inside or outside use
- a least one 1500 watt electric heater
There is no substitute for great storage capacity in any RV ... even more so in a small RV.
Most of the stuff in my list above is carried way down low, so it's weight only helps to "better anchor" the RV in high cross winds. Also our Class C is built on the Ford E450 chassis, so the total width between the outside tires of it's rear duallies also helps with side-to-side stability ... as compared to the narrower Ford E350 chassis rear duallies and the quite narrow Sprinter based and other small van based Class C motorhomes. Our small Class C handles superb and pretty much "drives like a van" - especially when I have it's transmission set to it's more responsive Tow/Haul mode.
