Sorry to hear you have problems but join the club. Have 2019 30X which is in the shop since Oct as it is nearing warranty ending next April. Over the past 2 seasons we had a number of issues, jacks failed (wiring fell off), alignment needed, awning lights (2X), water leaks (lines not tight), shower drain disconnect, seat cushions, driver seat not aligned to steering wheel, power step sensor, DVD player failed, side cameras replaced due to fogging, blinds shake off, furnace quit when 3C...etc. Many things I fixed my self because dealer is useless and unit was in shop more than used.
Soon after jack problem, I crawled under the unit to see wires hanging down. Took tie straps and tied up all the loose wires. While under there, find any water lines and tighten every connection (they will leak eventually). Then, get under the sinks and hand tighten every connection, make sure faucets are tight, they shake loose.
Good luck and hope you don't have the problems we did.
