Found a mobile RV service that is going to have a look tomorrow and ensure it's good to go. Keeping my fingers crossed.
This is a different style of Trillium
4500 than I've seen previously. The front, street-side corner has a built in toilet and the front couch isn't there. Instead, it has sort of a flip-down bench that's stored inside of a cabinet. That will all be coming out anyways, but definitely a bit different than what i've seen in looking at photos here.
