Took my 2016 28RBDS on it's first outing last week. Everything worked great and the dual A/C's kept up in the Texas heat. We only ran one most of the time. The only glitch was a flat right front tire discovered when I brought the slide out in. Called Jayco Roadside Assistance and was on my way in 45 min. Had a great time and can't wait to go again.
That's how it's supposed to work. Glad you had a good time. They don't always turn out perfect, but there's a reason people keep doing this over and over again....
Congrats on your first trip! We ordered a 28RBDS back in November - took delivery in December. Only issue we had was the awning LED strip went out. You might want to check out under the vanity and kitchen cabinets for leaks - we discovered one in the kitchen. Nothing serious - just had to tighten the supply lines.
Absolutely love the floor plan - the bathroom is awesome. Looks as though you have fiberglass - probably will be easier to keep clean. Enjoy!
