I’m not a super tech guy, know just enough to break more things. Just letting you know, if your jacks stop working for no reason, there is a little circuit breaker that has a small reset on the box. Check this first before calling for help. I got stuck with trailer on truck and jacks partially down. Paid 150$ for Rv repair guy to track the problem down for me in about 10 min. It has happened a couple times to me since. I’ll add a picture of where to look, but it is a small switch that needs reset, so look closely when/if it happens. Might be something you already know, but might save some stress and money. We love ours, good luck to you!
