I purchased a 2021 Milestone 379FLML in August of 2021. First trip out the hot water heater and TV wouldn't work. Took trailer back to dealer, they replaced something in the hot water heater assembly, and by passed the antenna to get the cable feed to work. Second trip out the oven wouldn't light and the middle jacks wouldn't extended, as well as the auto level was off. Was told had to hold the pilot light in longer to get oven to light, jacks were working properly, and the auto level was corrected. Upon arrival, after using auto level, still wasn't level, waited an hour to get it calibrated. Third trip out the hot water heater went out again, had water leaking under my island sink and water under the sink in my half bath. Called mobile repairman out to diagnosis the hot water heater issue (blown fuse able link, bought three from RV dealer intown i was in), had to replace the plumbing coming from the sink into the p trap as it was cut 1/2" too short and wouldn't stay in the pipe correctly. The plumbing under the half bath sink wasn't secured correctly and filled the underside of my trailer with water. Upon raising the front of the trailer to hitch to the truck, water ran out of the back of the trailer like a boat coming out of a lake. Fourth trip out the sliding barn door to the bathroom feel off the rail (happens every trip), cabinet door to the pantry fell off along with the door to the washing machine, two wall panels have come completely unattached their supports. I'm getting really frustrated with this, every time i go somewhere i either have to fix something while I'm camping, or as soon as i get home i have to fix something. I am concerned about the quality of the product i spent my hard-earned money.
