Just read the information on belly/plumbing problems. I have 2012 Alpine 3555 RL. Have had several conversations with Keystone customer service, and am still an unhappy camper. I purchased in Feb 2012 and first time out had problem with stove, holding tank table, and a curtain issue. Dealer fixed all problems as they were under warranty. Now almost 18 months since purchases, am in Big Horn mountains with another major problem. My black tank developed a leak around the intake port and filled the underbelly. I was on road and when I first noticed, pulled into campground to check and maybe fix. Had to drop mat of underbelly too found that Keystone had used it for a trash bin during reconstruction--two insulation wrappers, over 30 feet of blue and white electrical wires, and busted crimping tools. Anyway, finished dropping underbelly matting to clean out and trace leak. Found leak around the intake port, have tried a variety of sealers but still not luck. Still have the leak. Have called Keystone and am told that it has to be diagnosed by a Keystone tech at nearest dealer--am 70 miles from nearest dealer. Contacted dealer and was told that Keystone had 6 different tanks that match my model
--they need to see to determine right one, order time is 7-10 days, cant get repair appt for three weeks...so here I sit draining buckets.
My issue is that Keystone rep basically told me that I don't know what a leak looks like as they are the experts. I don't have to be a medical doctor to know that I have a broken leg. When I get home, I will take it to my local dealer, get it fixed, and sell it. Never will buy a Keystone product again....mostly because their customer service sucks!!
