I have a 2016 364TS and installed it in the baggage compartment under the fridge. Looks like it was made for it because there is an electrical outlet in the compartment. I drilled up through the floor with a hole saw and installed the Vroom RV hose under the fridge and over the furnace. I understand this will not work for you because of the double slides but I'm sure you can figure something out.
The Vroom RV is pure genius. Simply pull out the hose out when you need it, latch it in place, turn on the vacuum and go about your business. When done, unlatch the hose, put your hand on the end, and watch it stow itself! I still giggle like an idiot every time I use it. It a real crowd pleaser too.
Another advantage of the system is that the whole hose assembly installs in the wasted space.
I bought the Vroom combo kit for $300 from
rvupgrades.com. For some reason I could not find the kit anywhere else, saved over $100. For those of you who already installed the Dirt Devil, I believe you can buy the Vroom RV hose system separately. By the way, you need to create an account to see the lower price, I think they have to follow Dirt Devils MAP policy.
I don't like Mark's installation, mine seemed a lot easier
