now Hollis ,, u contribute alot on here ,, and u do make some good points ,,, no one ,, IMO is an expert on here ,, we all just put our 2 cents in of what we know or have been thru ,, and that's it ,, yes a few do deal with rvs day to day ,, like ken ,, and Nash ( our resident fulltimer expert) ,, i myself do know a few things ,, but i am outta the rv repair business ,, but i do try to keep up with the changing matters on newer rvs ,, mine alone is a nightmare ,, i am still learning it :concern:
