Yes I have. In fact, I am waiting for my new Heartland to arrive, having just purchase it from Chesapeake RV Solutions. Tim and all were extremely helpful, answered most of my questions, put up with a lot of hem-hawing from me and finally worked what I think is a pretty good deal on a new Landmark Pinehurst.
My current 5er had a gooseneck adapter on it. I really didn't like the way it pulled. Tim got me a B&W Companion hitch for my turn-over ball and I couldn't be happier. Every thing he told me about the difference from the gooseneck to the 5th wheel hook-up proved to be right on.
His openess and willing to work with me is what sold me on buying from him verses one of those "discount" dealers. Funny thing is, I got a better price from Tim and Chesapeake RV Solutions than I would have gotten from the "discount king."
