We just bought our 3450, 2015 Big Country RV and had a few issues to deal with. First off the dealership had someone walk us through our RV and explain how to use and work all the elements. Now we are not newbies to RV's as we had a 2006 Sunnybrook we traded, but as there are so many new features we had some things we were not aware of. First off, the 4-way switch for the water was new. Now the person that walked us through, obviously did not know what he was talking about, as he told us to switch it to "normal" in order to have water from a tap hooked up to the trailer. WRONG. We couldn't get water to go into the trailer so John(husband) turned switch to "sanitize/winterize" and presto, you could hear the water go into the trailer. Now thinking that this was wonky but who knows, we left it there. I had purchased a washer/dryer combo with this unit and wanted to try it out at home to see how it worked. Well needless to say the next morning we woke up to the underbelly of the trailer bulging as the water overflow(from what we can tell) had seeped the water on the frame and then filled the underbelly. What a mess! So John being a very handy guy, unscrewed the flooring to allow the water to escape and dry out. No damage was done, and we were very lucky that this situation turned out as good as it did! So now we have put an extension on the overflow from the tank(more than likely never need to worry about this again) but you never know. Thank God for you people on here, as when we called the dealer there standard answer is to "read the manual", and we had no idea on what to do with this 4 way switch. So after asking on here, they told us about the "city" switch setting, which we never saw as the handle was over top of the word! DUH! So all is good now! But when John was under the trailer he discovered that there was a brace not attached to the fender under the kitchen table slide. So this is now attached! Also the spare tire bolt was seized, so this is now repaired! Once a year we do dry camping and we were concerned with the household refrigerator in the unit that it would not stay on with the battery charge. So we purchased from the dealer a solar panel and had it installed. Since then John has purchased 2 more batteries and installed them to insure we have extra storage for battery charge, while driving to AZ this winter! So now the next project is to add a towel rack in the bathroom, tho we are trying to figure out what stain has been used in the trailer to match colours. Thanks for listening to my book! We do LOVE our Big Country and look forward to spending a lot of time in it. Take care. Sharon
