Not sure if your interested in the Prime Time Crusader, but I am waiting on delivery of a 330MKS that I purchased from Terrells Camping Center in Terrell, NC (30 min N of Charlotte). Great prices and really nice folks up there.
I wish you the best in finding the right unit. The Sandpiper is a sweet rig!
