Definitely did not buy an ACE.
Wish we had bought a Newmar - much better build quality.
Insulating the water lines, especially those outside the coach (which is a mistake in and of itself), is so the coach can be used in colder weather. This is definitely not a 4 season coach, but it could be.
We ran into several occasions on our trip outwest where another couple inches of clearance would have been greatly appreciated.
Padded carpet is to help reduce the road/engine noise. It can be stapled and glued down, just like the current small/thin pad, to avoid bunching up.
You are correct the 2015 does use the same countertop throughout the coach. In 2016 Jayco took a step backward and used cheap counter materials for the bedroom, bathroom and event the table. Not a good design choice.
You are correct the 2015 and 2014 do have a nice lock. The 2016 now has a keyless entry pad (cool) but the deadbolt which can only be locked/unlocked from the inside is gone. Now there is just one lock with a rather small/thin bolt. Not a good design choice.
You are correct the 2015 model wardrobe door do clear the bed even when the slide are in. In the 2016 29UR they no longer clear the bed. Not a good design decision.
Agreed Jayco's choice to go cheap on these items make it sound and feel more like an ACE - all to presumably save a couple of dollars....
