We have a 12 model, and the sewer hose issue is a good one. They provide space for a 10ftr but thats it. As to a ladder Mine has a full width trunk and no ladder is available so will have to use a portable. Storage space inside is OK for us, but outside is limited so have to really think on what you need to carry. No room for lawn chairs etc. Wife and I do not care for the round dinette setup, wish we had a regular one instead. May try to replace near future. The rear slide out bed does not have any under bed storage capability dont know about the one you are looking at. Overall its ok, oh yes no real insulation behind the fiberglass over cab section. Took the stereo out as it kept sliding around and saw that. Does make a difference in heat cold in the coach. Will need to figure something out on it also.
Also unless they changed, the air shock inflators are hard to get at and need to be adapted for access. Again ours is a '12 so there could have been changes. Hope they finally got around to adding power seats up front. Ours rotate for what that is worth (not much IMO) but are a PIA to setup. In reality much more impressed with the Jayco line but they too also had their issues with storage etc. Monaco were just flimsy all were class B+.
