Hi Rraulston,
Welcome to the Heartland Owners Forum.
Lippert has several offerings; at least one of which should apply to your trailer.
Here's a link to their flyer that's showing what's available at special prices to
Heartland Owners Club members attending the
North American Rally taking place right now. You'd have to contact Lippert to determine whether the rally special prices are available to you, or just to club members, or just to club members attending the rally. And they can also tell you where installation can be done.
