So we bought an adaptor thingy that turns a cordless drill into a “stop knackering your back winding the corner legs” doodah. £5 from The Caravan Shop, Gt. Western Rd. Now all we need is a cordless drill!
There were quite a few in Homebase, ranging from cheap and cheerful to black and yellow and menacing. The kind if thing Darth Vader would use to tighten his scrotum bolts.
Settled on a cheap one and was surprised when it came with Mr Happy Charger! He really wants to keep your battery charged!
