Our opinions on class A's vs Class C's: Class A's have massive windshields that let in too much glare and heat, expensive to replace, no shade from the overhead as with a Class C. Service/repair not always available on a Class A's, more available on Class C. Not as much protection in a front end collision in a Class A. Large Class A's limited to resort-type RV parks, seem out of place in primitive campsites and public parks, event parking lots. Other than above, a 27-30 foot Class A or Class C can have similar floor plans and sleeping accomodations. Generally, Class A's appeal to couples and Class C's to families.
Some Class A's may have better ride than Class C's.
