I would compare the "Dues" charges and look at your long term plans.
Wife and I plan on traveling a good portion of the US, from the east coast tot he west coast (In fact we have been all the way from Provincetown, MA (Cape cod) to Los Angles already) and from the Canadian border to the southern shores,,, Thus the lifetime, national membership is the thing for us... And as full timers we make good use of our membership.
Dues, for us, around 45 dollars a month.. ONE night in a low-end KOA,, about the same (45 bucks) so you do the math,, I spend 2/3 of my Winter in a TT park and 1/3 of my summer (different parks) Even when we get to our major traveling in a few years I'll be spending at least 25% of the time in TT parks. So it's an investment for us.
FOR you...... Well, you need to do the math.
Oh, and of the parks I have stayed at: (Saint Clair, MI, Las Vegas, Carolina Landing, and right now Indian Lakes) I have only nice things to say about the staff.. Very nice things in fact. Some of the other parks I have stayed at, Let's just say I am not so happy with the staff.
I can tell you this: Most of the TT parks I"ve been in are older parks, Today's really big I mean bigger than that, rigs may have issues with some of the parks.. Mine is 38 feet and I do not have a problem.. But it's occasionally tight.
Home is where I park it!
