We own a 2016 Berkshire 38A. I can honestly say we looked at all comparable coaches when we were RV shopping. (Tampa RV show has Winnebago, Tiffin, Newmar, etc.).
As compared to the Winnie 38R: I can honestly say we thought the Berkshire was a better, more sturdy build. For example: bedroom/bathroom walls: if you push on the walls, some coaches the walls visibly move. Not in the Berkshire. The walls are very sturdy. We also thought the overall interior fit and finish quality was better in the Berkshire. We also have a kitchen slide so our overall kitchen/livingroom area is larger.
The 38R has a similar floorplan to the Berkshire 38A although some of the differences in the 38A may make the Berkshire more user friendly. For example: it looks like the placement of the washer/dryer in the Winnie 38R is going to eat up a lot of space. In the Berk 38A the stack W/D have their own cabinet (to the left of the sink) which leaves the area to the right of the sink for a HUGE linen cabinet. I fit all of our towels with plenty of room for beach towels too! There is also a large medicine cabinet above the sink and storage below the sink so storage is DEFINITELY not lacking in the Berk 38A!
The bunk area in the Winnie 38R is a little different than ours too. It looks like the bunks in the Winnie 38R are: upper 30 X 72" and lower is 31 X 65". In our Berk 38A both the bunks are 30 X 70" and the upper bunk does fold up and there is a curtain rod across the bunk area which allows for great extra storage of coats. When we compared the 2 coaches the bunk mattresses in the Berk 38A seemed to be better quality foam and the doors across the bunk area seemed to be better quality wood. The doors also fold away really nicely for ease of use. The literature for the Winnie 38R says "Multi-purpose room with Flex bed system". I am not sure what that means, when we saw one at the show both bunks just looked like bunks. (FYI we use a featherbed on the bunks which makes the bed really comfortable! It is made for a fold away cot so it fits the bunks nicely. PM me if you would like the website info for purchase).
Our Berk 38A is on a Freightliner the XCR chassis (raised rail chassis) and the Winnie 38R is on the XCS chassis. So we have more useable basement storage due to the raised rails.
Our Berk 38A has more tank capacity: (Fresh water, grey tank, and fuel tank).
Having said all of that I can truly say we love our Berkshire 38A and would definitely buy it again if we had the choice. Our fellow Berkshire Owners have also made our decision a happy one. Everyone is very nice, helpful, and welcoming! They make you feel like you are part of a family even before you take delivery of your new coach! It really makes RVing fun when you have a fine, well built coach and a great group to camp with!
Not to sway your decision or anything..... but I can promise you if you choose the Berkshire 38A as your new coach you won't be sorry!
Good Luck with your RV search!
