We used Chesaco for a pop-up a couple years ago, and we just put in an order for a North Point 377RLBH this past weekend at the same show.
They were good to deal with on the pop-up. Straight forward with pretty much everything. PDI wasn't overly extensive, but he stopped to answer any questions without making us feel rushed before letting us try it all out to our hearts content. It came in with a couple scratches in the awning, and they had already had the replacement on order when we picked it up.
Being up 83, it seems that either Joppa or Frederick is not completely in your way for warranty service, but they do have the 2 locations so if one is backed up, may not hurt to inquire about the wait at the other.
