There was 1 other minor issue, when trying to grease the bearing the zurk fittings wouldn't take grease.It seemed the factory had somehow crushed the head of the fitting and the ball was not releasing to accept the grease, just a simple change of the fittings was all, and this summer will be our 3rd summer using it. You can see the number of night using it, and our main vacation is usally about an 800 mi round trip and then about 3-4 shorter 150 mi round trip trips, so we figure about 1500 miles a year towing it. Main reason we selected this floor plan was same as yours - walk thru bath with more floor space/room.
