Hello! I had originally posted looking for a class C, but now we are looking into a used Class A. We are looking for a starter RV to travel some long distances but it would usually sit thereafter for about 8-13 weeks. It will also be towing a small car behind it. Which engine is better? Gas Ford or Gas Chevy? How old is too old? Or, should mileage be looked at before age? How many miles is too many miles? Is it better to buy from an individual or dealership? Also, does anyone know of any honest dealerships in the DFW area? Also, what info can someone provide about generators? Thanks!
