I would stay away from buying into a park membership program that can cost several thousand dollars.
There are so many deals out there with Good Sam Club, Passport America, Escapees, etc.
I was just at Summer Breeze RV Park in Iron Mountain, Michigan, and got 15% off the rate, because I'm an Escapees member.
It was only 10% off for a Good Sam Club member.
I belong to the 3 that I mentioned above, along with the Senior Pass for the National Parks and Federal Recreational Lands.
I'm a Life Member of Good Sam and Passport America.
If you plan to do this for many years, it may pay you to get a Life Membership.
Most of these memberships run in the neighborhood of $50 to $75 per year, but some of that is returned to you by way of discounts at the parks etc.
Buy a copy of the Trailer Life Directory by Good Sam Club (if your a member, you get a discount) and this lists most of the campgrounds and RV Parks in the US and Canada.
CAUTION, should be the prevailing word here, do your homework, and don't jump into something you may regret later.
Don't be pressured into something by fast talking salesman.
Don't ever be afraid to ask questions.
There are no stupid questions, just stupid answers sometimes.
Take your time and enjoy the view.
Your kids will have memories that will last them a lifetime.
When my 2 grandsons were 8 and 4, the 3 of us would go camping at a state park on the beach. We would swim and hike the trails. They talk about that today, how much fun they had back then. They are now 16 and 12. Hard to believe, the oldest one has a drivers license now. Time flies.
I would say if you had to pick only one (1) my vote would go to Good Sam Club.
Also, you can't ask for a better members forum then this Heartland Owners Forum.
These Guys and Gals are the Greatest.
Some Heartland Brand Mangers (maybe all) are also on this site, so you have the company listening to what is being said about their products.
Welcome aboard, it's a great ride.
