Why a class A gas over class C?

I think how you want to use the MH will determine which is your best option. You have gotten a lot of good advice so far, you need to ask yourself what kind of camping you are going to do. Are you going to stay is private CG's on mostly paved roads with full hookups? Then ground clearance and water storage doesn't mean much. What size MH do you want? A 30 ft or less or a large 40 ft MH. How long will your trips be? W/E trips extended 3 mo trips in the summer? Do you want to carry a lot of stuff like bikes, fishing gear, rafts etc then large storage is important. How many people are going to travel with you? Once you determine how you will use the MH it will be easier to decide which one will fit your needs.
