I don't like the idea of renting because with certain modifications u can get so much more out of your rig. For ex in motion satellite dish makes the ride great for kids
Not to start a war but ford v10 tends to run at lower rims than Chevy v8 but has more heat in compartment.
Floor plan is the most important thing. Find a floor plan that works for u. Most class C have similar frames, suspension, and engine unless u get into sprinter or super c.
For weekending a 29 ft class c is more than enough. People move up to class a gas engine for anything over 34 ft and to get more cargo carrying capacity and bigger storage tanks. People go to diesel pusher usually over 35 ft because in general u tend to lose too much power in a gas class a transmission of that length although the newer gas class as are going out to 39 ft. The only limit to a class c is sometimes cargo carrying capacity and they don't come over 33 ft or so unless u go super c
I like my c because the overhead bunk is great for kids and storage and u don't have to make bed back into dinette. Some class a do come with bunk in front
If buying used have it inspected by independent inspector not just dealer.
Class a diesels usually have air brakes and air suspension which give better ride but with bis twins shocks, anti sway bar, and steering stabilizer my class c rides and drives like a suburban. Highly recommend at least those three mods if for no other reason than safety. The improvement in ride and handling is amazing
Not sure if gulfs tram is still maying class c but with only 3600miles shouldn't be a problem. There are lots of used units out there so take your time
