My advice; get a mad mats carpet set in the front, some original looking seat covers, buy a second hand or cheap r&r bed and install in the rear with nice oem-ish covering. Take some better pics (e.g. In the sunshine on the top of a hill surrounded by super countryside with a set of camping table / chairs if front with red-white checked table cloth, wicker hamper, champagne bucket, ice and flutes etc). Ask £9,750. Newbies want to "live the dream " so you need to show your van will give them that. Ready to use van will sell much better than one that needs finishing (and the cash you'll spend to get it there will be more than recouped IMHO). Good luck with the sale - amazed this hasn't gone yet.
