Just took our 2018 31 UL out for a weekend to a local state park. All systems performed perfectly. Nearly locked ourselves out when my wife entered in the wrong code for the electronic lock.
Just thought I would share some good news on the forum.
We just did the same. Did a week at the Grand Canyon (no crowds) and then Monument Valley and Moab Utah. No serious issues after a winter of storage and a great trip. Now getting ready for 3 months in Alaska.
