Never used 2020 Grand Design 399TH Toyhauler triple axle 21k GVWR. Can control everything wirelessly. Ordered the RV with custom options that Grand Design used  to showcase at RV shows/events. Added all the supplies and accessories to go camping but the actual unit has never been used or stayed in. It has been showcased at events and then stored at a RV dealers facility who has done the maintenance on the unit religiously. 
Cummins Onan 5500 generator.
3 A/C units.
2 patios (side patio & rear patio w/ awnings).
One Control touchscreen to control everything.

Wireless control everything from lights to A/C’s.
All beds have new memory foam.
Super sofa.

Dark color leather seating.
2 bathrooms.
Large loft.

Inside and underneath lights that change colors.
Three large awnings.
Two large patios. 
Four TV’s.
Rockford Fosgate Audio.

Comes with just about everything to go camping from seats, soaps, dishes, cleaning supply, vacuum, water filter, water regulator, sewer supplies, drinking water hose, sewer water hose, volleyball net, etc.

This unit is turn key and ready to go. You can control everything off of a mobile app from anywhere you are. Turn on the A/C and outside lights thirty minutes before you arrive at the unit or the opposite. It is also the most expensive model (399TH) Grand Design makes. I had it built & the camping accessories stored in it to use but due to going through a divorce, I would like someone else to enjoy this Toyhauler. My loss can be some families gain to get closer to one another.
