Picked up new 3100 RD last week, took to nearby park for "check out" weekend. Was really impressed with GD and dealership QAQC. Had zero issues after running all appliances, systems and mechanicals. 7' longer and 3000# heavier than my 2600RB, but towed great behind the F250. Much more room and two extra beds (tri fold couches) BTW, paid $23k for used 2017 2600RB in Aug 18, sold for $21k. GDs really hold value after the 1st year depreciation hit. Will report back after several planned trips.
