Searching, good to hear from another Michigander. You've already got one of the finest hitches made - by all means, keep it. That's exactly what I have.
One word of caution, though. Make sure that your Heartland dealer installs the capture plate with the bolts provided. Mine took the easy way out and welded it. Now, the pinbox is useless, except for another Pullrite owner. This is especially important if you decide to change the pin box to another supplier, like Trail Air - you have to order another capture plate from Pullrite (as I had to do, and guess what?) - LSI (the company that Heartland used in 2006) welded that one on as well. Yes, it is a lot harder to install the capture plate on with the bolts, but insist on it.
