My wife and I are about to take the plunge and purchase a 5th wheel for our retirement to ourselves. Any input as to which manufactures/models are a waste of money as to which ones are a great buy; ...
You should go ahead and start looking for a good, 2 or 3 year old, used F-350/3500 diesel truck. (unless, of course, you already have one.) Anything less will limit your choices severely in the size range you are talking about. High quality is never light.
PS..Has anyone seen anything from the OP recently?
