We have heard that RVs made since the start of Covid have had lots of problems.
In the Garden of the Gods RV Resort, our neighbor, Ron had bought his 5th wheel travel trailer new one year ago. He has had 35 different problem including an AC that does not work and a water heater that won’t shut off.
Each needed to he checked, tweaked and assessed. With each problem the manufacturer eventually agreed its broken and would order tye parts to fix it. When he asked when the parts would be in, they would say they have no idea because they are back ordered.
He will probably have everything fixed on his RV by the end of the year. That’s when his new house will be complete. Hopefully the housebuilders are more diligent than the RV builders have been.
