We have one installed in our 37FB. It too fits sideways and impacts our closet storage a bit. We lost 2 feet of closet rod space with the installation. I've compensated by removing the fairly worthless 4 drawer chest that was installed on the opposite side of the closet.
We had it installed by the dealer with no issues getting it in or setup.
So far, no issues. Works as advertised and acts just like the set at home, in regards to cleaning and drying times.
Don't put anything on top. The washer spin cycle will send it to the floor. I unfortunately picked the worst thing to find out that particular issue. Full bottle of liquid laundry detergent. Took me 2 months to get rid of it all. But I have really clean carpet now.
If you use a lot of hanging clothes, you'll fight the w/d to get stuff in and out.
We use the dryer as our dirty clothes hamper.
Once installed, you can't get to the water or drain connections. Make sure they leak check before you drive away.
Our Trilogy is configured for the washer to drain into the Black tank. That was really interesting and fortunately, discovered quickly. Was outside and didn't hear any water draining. Checked the toilet and found water coming up the pipe....yikes!
We love ours today. If any issues start up, we'll update on our love affair.
