We also have a new RC25. Been on a few trips including a week at Rubys Bryce Canyon. I like the performance (downsized from a 35ft gas class A) especially since we climb 6,000 ft out of Phoenix going north and pull our Wrangler.
I have improved the handling by putting on larger Helwig anti-roll bars front and rear. Still want to add a new steering stabilizer.
After the Class A I miss not having a leveling system and would like to add one.
I also added 200W of solar panels and find that we can camp for days without using the generator unless the microwave or hair dryer are needed
Overall the space when parked works really well for my wife and I.
