We have bought a van!

Hi everybody, we have been camping for a few years and now have purchased a caravan, quite an old one 1994 and it is on a permanant pitch at the moment. We will use the van at this site until the end of the season, but then will have to make a decision over whether to leave it or move. This is based on how feasible it could be, does anyone recommend a caravan 'service' company in the Selsey area, who could come give it a health check? Any other advice greatfully received thanks
