How much weight does the typical slide out add to a class A? Not sure if selling my 2000 Class A and paying 10 K more for a another one of the same year with a slide would be worth it as our dime is pretty thin. I guess it depends how much I value the extra room. I would think there would be more air leaks and maintenace with one. We would be living in this unit 6 to 8 months out of the year. If money was no object, I wouldn't even have a question. Your thoughts, thank you. Fred from Pasco, Wa.
