Because of the way these things are built, the only feasible way to do this would be from the outside. Well, you could do it from the inside, but it would be about 10 times the work and you would certainly be guaranteed damage to the walls and cabinetry.
The good news is that the siding is a piece of cake to work with. All the trim is screwed on, the windows are screwed in, and the siding is attached with common staples. The roof is a different story.
That said, I'm not sure it would be worth the effort. You might pick up 2 R at best, and you would be looking at at least a $500 investment by the time you bought foam and butyl tape to reinstall everything. If you were a hard-core winter camper and wanted to do some other upgrades like thermal windows, then it might be worth it.
I wish there was an easier way into the roof because when running wires I had found some sections in my Sunline that are completely non-insulated. If I run the furnace on a snowy day, they really show up in the snow melt pattern - even more places than I had found too.
Just my $0.02..
