What I want to do,, and whish they would do it,, would be,, to make the dog house removable. My Holiday Rambler and my old Superior have a box under the couch (HR) or under the back right side bed (Superior) If you can make it removable like the engine you could get to the whole Genny and be so easy to service. I don't know what a Marquis is but I am used to the emerald. I may be getting a 1982 pace arrow,,, with either the emerald or marquis, I forget. but I may design a removable gen box.
