Check out OP4 website for all the details about the rig https://www.opuscamper.us/op-4/
We (wife and two kids 8 and 7) used the OPUS 6 times before I started my own company and now I don't have time to use anymore. This is a 2020 that we purchased in Nov of 2020 from Big Sky RV in MT. I'm asking $33,750, which includes Air Annex, Go Power 130W Solar Panel, Fold over cargo-rack, rack mounted shower & Ironman 4x4 tent. The AIR Annex system includes two extra bedroom pods and provides a large additional living area. Adding almost twice the space, the new lightweight OPUS AIR Annex is a great way to make additional room for everyone and provide extra storage space.With all the add-on this rig will cost almost $38k-$40k depending on when you can order and receive. You can have this rig today and save $5,000 or more.
