What do you recommend

Our caravan is getting on a bit( Avondale Mayfly 1989) and in the next year or so we are going to buy a a replacement. We will be looking for a used van. We are not in a rush( as the Mayfly suits us fine but of course at that age things may start to go wrong) but are trying to compile a list of suitable models so that we can start to search. I guess we will be looking at something over 10 years old so its difficult to know which models will fit our criteria. Our budget will stretch to £5000 absolute maximum.What we are looking for is a :-2 berth tourerMax length 5m( not including towbar).End bathroomBuild quality to match the Mayfly.Does anyone have any recommendations.
