What size are you looking at? How do you want to camp? Short trips? Months at a time? In FHU CG's or NP's or SP's with no hookups? How many people will be camping in unit? If you can answer these questions I think you will get better advice. In general a short Class A will have better suspension, more storage and more water compared to similar size C. If you want to stay short say 23- 26 ft a Class C with a full wall slide will give you a lot more room inside and a queen bed. If you are looking at say 30ft or more I would go with the A, but everyone uses the MH differently so tell us how you plan to use it and that will help you decide which one will fit your needs better.
