Work done while in Storage - newbie

I don't think a caravan site would allow you to do work on a van as most don't allow cleaning of them. Also I would visit the storage site your looking at and ask them about working on the van but using their power might be a no go so cordless tools might be a thought. 

You might perhaps be better to see if a CL owner or farmer local to you would allow you to store your van on their premises and for a price supply you with a power supply so that you can do the work you want to do.

If I was you I’d get this sorted now, RA. Storage sites often have waiting lists and holiday sites are very full at present. You're cutting it fine.

I would certainly get storage sorted as soon as you can. When we bought a caravan in 2005 local storage wasn't that easy to come by and it still isn't. We put our name on the list of a local storage and when one became available rented the space for a month before we got our van.
