I have a new 26RR. Looked at the 22RR first but liked the window. Valkyrie fits easily so even a trike should fit.
Not so much new stuff but several mods are handy. Add shelves under tv, longer screws in tv mount, foam mattress, shocks on bed trap door and cupboards that open up, redo straps on couches so you can store backs on top when folded up. I added 2 ' to the tailgate and put on longer bumpers so bike would not bottom out when loading. I moved the slinky storage to the tongue and added a battery.
Some things to add as you go along. A couple of water hoses, hose gaskets, pressure regulator and filter. Surge guard, 30 amp to 20 amp adapter and a heavy extension cord, leggos for the jacks, wheel chocks and misc blocks.
Word of warning. Don't let better half go to rv store alone with cc, don't ask me how I know.
Enjoy, you made a good selection.
