My husband and I used the Grand Design Toy Hauler for a couple of months last Winter. Our plan was to live in it for the Winter in Florida and then bring it back to Vermont in April. Enter Covid-19. We drove back in March and only used it a couple of weekends in Vermont (no out-of-state travel). So, it's essentially a new rig. Everything works. I am happy to send additional information and pictures and answer any questions for anyone that is seriously interested. It's currently winterized and sleeping for the Winter months.

Here are the specs straight from the dealer's website.
