We have a Rockwood Signature with two slides, one in the living room/kitchen area on the drivers side and a second slide for the bunk room on the other side. It has a half bath across the rear. The sticker price was $37,000 on it in 2011 when we purchased it for less than that. We have taken several two and three month trips in it with our two grandsons, ages 11 and 12 currently. Worked fine for the four of us and occasionally our daughter, the boys mother, would go with us or meet us somewhere.
I would suspect that the OP is going to be looking at a price about triple
or $75,000 give or take and working with a custom builder to get all the features mentioned. By the time all the features are added, probably looking at something close to 40 ft in length, which would need a bigger truck than what we are using, a Chevy 3500 DRW diesel crew cab, LWB 4 x 4. Think I saw something about Nexus RV was going to start, or has started to build some 5th wheels. Never had one of their rigs but understand they will work with a buyer to custom build much of the unit, as long as the buyer has the money and willingness to pay for the custom work.
