Hi. I know I'm really late to the party, but I own a 2018 Mesa Ridge 2910RL.
We're very happy with the trailer, but we have had our moments. If you've already made the move on the unit, here are a couple things to watch:
1. I'm really anal about maintenance, however I did find a hidden area that I missed which resulted in a $6,000 replacement of the passenger side slide floor. If you check on the outside where the slide sidewalls meet the floor, there is a small piece of metal trim on both the front and back of the slide. After I noticed some soft spots in the slide floor, I removed the trim only to find that there was an insufficient seal between the metal trim and the side of the slide. This caused the trim to channel the water directly into the slide floor. If you catch it before there's any damage, the repair will only cost you a few dollars - a second layer of butyl tape between the metal trim and the slide will seal up the screws nicely and prevent the problem I had.
2. I ran the trailer up over a curb (drivers side) and found that it caused the cable carrying power to the rear motor on the driver side slide to break loose from the slide floor (it was held on by zip ties only). The cable was riding on the tires as I was driving and they stripped all the insulation from the cable and the inner wires. The result was a shorted out slide motor and the need to replace the cable. I got the motor from Amazon and ordered a new cable and some metal clamps. It took about 90 minutes to replace the cable, motor, and secure everything away from the tires with metal clamps.
3. Driving on I-95 from Jacksonville to Savannah, I had one of the original Chinese tires blow which destroyed the tire and wheel skirt. I replaced the wheel skirt in about 15 minutes - it cost more to ship it to me than to buy it (less than $100 total). I replaced all of the tires with Goodyear Endurance tires and added a tire pressure monitoring system. I haven't had an issue since.
I know these things sound major, but I've written them all off to the joys of RVing. The only one that wasn't at least partially my fault was the leak I described in #1. We really love our 2910RL. We've spent over 500 nights in it since it was purchased early in 2018. We usually spend at least 90 nights every summer. We've taken in from Florida to the Upper Peninsula of Michigan three times. Last summer we traveled over 7000 miles with it. We use it at least two weekends every month. We're always looking at new trailers and 5'ers, but still haven't found a single reason to switch from our 2910RL. It's perfect for me, my wife, Golden Retriever, and Dachshund.
Happy and Safe Travels!
