It is necessary to have a generator in a 5th wheel, I know some have them some don't. We are looking to go to a 5th from our class a and we really don't use ours a lot now.
Thanks for the info, this was not even something I was aware was an option until recently. All of our 5th wheels have been in the 30 ft. range and used mostly for weekends and 2 or 3 yearly vacations so I guess we had not given it any thought. We will need to take that concern out of the con column for 5th wheels.
