First time ever posting in a forum, so sorry if this ends up in a weird place. Just wanted to offer up my help when it came to self install of a washer/dryer in the 377. I was beyond frustrated with the lack of information out there to help, and looked for a long time on here only to find similar frustration with self install of the dryer vent. One aspect should not prevent people from being able to install things themselves! So after much deliberation and a lot of luck, I just went for it. So here is my quick run down of the whole install:
1. Dryer Vent. The self install dryer vent seems to be the biggest thing tripping people up. It was my biggest leap of faith, and paid off! I ended up guessing where i wanted the vent to go. I chose left of the drainage pipe. Hopefully these photos attach so you all can see. I started carefully with maybe a 3/8" drill bit and did an exploratory hole. I went until i hit foam, then attached the coring bit and used it to make an outline of the proposed hole. I then did test holes all around the perimeter to test for studs and supports and was met with success!! I actually believe (dont quote me) that there may not be studs in that entire area! long story short i was able to drill the hole for the vent all the way through to the outside.
2. Vent kit. We chose a splendide 2100xc washer dryer combo, which has available vent kits for purchase. With the hole now made, it was pretty easy to mount the vent from the outside and secure it with the included screws. I ran a generous bead of silicon sealant/adhesive to help with stability and add to weather proofing. Then i attached the white cover using the same method, and plenty of sealant. The location of the hole was perfect because it lined up with the vent exhaust on the dryer, and also left room for the outter cover to be mounted but not interfere with the trim near the nose of the trailer!
3. Install washer. Once the vent is in place, all the other hookups are normal and super easy. Be careful moving the machine into the area as it super tight. I believe I accidentally cracked the drainage pipe because water is leaking out when the unit drains. Looking for a solution to that, but dont worry that is definitely due to my spastic nature! Hope this helped! I took the risk to see if it could be done because i know it has been causing a lot of frustration, and frankly you should always be able to do things around the house! Thanks for all the other projects you guys have posted, now gives me things to drive my wife crazy about!!!
