Besides the fact Class A RVs don't need to be pulled, what are the advantages/disadvantages of both? Also, if I have a 5th wheel can I use it to tailgate just like those with a Class A? Do some have an on-board generator? I need some advice as I'm in the beginning stages of looking into buying one. Also, any recommendations on what to buy and what not to buy I'd appreciate. Looking to spend 30-50. TIA
