And more to the point, how do you know.. 
We're new to this motor home lark and were wondering about what stuff we need to buy to make life a little easier. We'll be pretty much living in it for 8-9 months a year, around central Europe.
We've used a caravan for many years, so there's lots of things that can be easily transferred.
I'm not looking for general accessory ideas, I just want to know if any of you live aboards carry around a collapsible ladder to gain access to the roof. I'm thinking of cleaning purposes and on the (hopefully) odd occasion for repairs/maintenance.
If you do carry such a thing, any recommendations please..?
