Interesting. I also bought Discovery LXE 40M 2021 and took delivery 4/2/21. We have had numerous initial problems also although the jacks have been fine.
Rear AC/heat pump buzzing with a bad relay only took 3 boards finally turns out the tech soldered the relay and at least for now problem fixed. 3 months later
DS slideout roller got crushed from debrie left in during construction. Cracked a tile near the drivers seat. Still waiting for completion there
Firefly system fried from a shorted wire from control panel to switch panel in the BR. Finally fixed
Jack pads are 9 inch and have bent from the weight. I am asking them to put on the 12 inch replacement and hopefully will fix it.
Circuit board on the Onan generator quit working while it was in the shop. In process of fixing.
Numerous fit and finish issues showing horrible quality control at the factory. We have had a Seneca HD for years and never had a problem so I thought I knew how to look over a new unit. We certainly love the look and feel and the freightliner chassis but I am not sure I would buy a REV group product in the future.
Maybe when we finally get it back after 115 day and counting in the shop I will again feel it is a good machine.
Contacted a lemon law attorney and am in process at this point. We shall see.
