Last time we went out, our slides were moving when raising the jacks. Tried many things, got frustrated and called the dealer and the sales rep. We ended up bypassing the slides to get the trailer folded up and went on our trip, dealer thinks there is trash of some kind in the lines. Everything works ok now, but our dealer is going to charge me to look at this even though the trailer is under warranty. Very frustrating as I have had to fix items myself while traveling and when our trailer has gone in for warranty work the dealer says some things are better off if I fix them because Grand Design wont authorize repairs.
