I have a front bunk out of a dodge if it's any use to you, the bars are extendable with 3/8 spigots on them, they go into holes drilled into the sides of the van.
£40.00 if you're interested + carr if needed.
Hi there, back from my hols, i'll send you a PM with the bank details, and get the bunk wrapped and ready to go.
Interior being transferred to Sunny next week, so loads of goodies to part with soon
