Don’t know about Pleasureway but the Roadtrek hose is 1 3/8” which is not a common size. 1 1/4” is more common but does not fit as well. The fittings are also available in both sizes.
Will post a link for the hose when I find it.

Check your hose size.
I had to tear out a good portion of the interior to get to that hose.
The problem is it passes through the floor and is permanently fixed there. You cannot pull it out from the bottom. Hope yours is different.
