Getting to running lights on Class C cabover

I climb the rear ladder, crawl on all fours to the front (I never walk upright on the roof - too much weight concentrated in the small spots where you step), and hang over the front edge with by head and arms.

I have had to do the above in a campground and once on the open road .... hence I'd never buy/own a Class C without a built-in ladder for roof access anytime anywhere on short notice!
