My family and I are just beginning our search into RVing. Here is our situation. My wife and I will have a couple children within a few years. My parents are getting close to retiring and are interested in RVing as a possible lifestyle. Therefore, we are trying to buy something that will fit both our needs (really just the extra bedding for children). We need help figuring out what would be best for us. I've excluded Class C's after reading how comparable their mileage is to an A and the probable inability to pull a car behind. Therefore we are at the point of arguing over 5th vs Used Class A. I've been going over in my head both ways. I have some questions I keep coming back to; MILEAGE:: First of all let me state neither of us have a Diesel pickup (I have a VW GOLF Diesel). Therefore we'd have to buy one, and my dad has thought about selling is lightduty pickup so maybe we could pickup the $20-$25,000 cost for a used crewcab. WHICH GETS BETTER MILEAGE? Gas Class A 30 foot? or 30foot Salem Fifth Diesel Pickup?. Also, in more detail how much does the Class A drop if I had to tow say my VW behind it. In terms of the Fifth I don't know what kind of mileage I'd get on the Truck empty. I've heard anywhere from 15 to 22 depending on performance chips, etc. Anybody have any realistic estimate and are any of the Big 3 known to get better than others. CONVIENENCE: In terms of setting up camp how much longer does it actually take to set up a fifth vs. the Class A. Also, this might be a stupid question, but does the TV play while you are driving a Class A (i.e. children's entertainment). I guess I'm thinking of the actual driving experience for passengers. COST: Insurance Rate Differences Between the Two? Maintenance Costs? FINANCING: Is it the same 15 year 7.99 type of loan? OTHER HELP: For the next five years this will be used for weekend getaways and possibly 2 weeklong vacations each year. Thank you in advance for all help.
