Still searching fcr a wagon upto 6.5k in and around Yorkshire (maybe further afield). Not too bothered about a living area. want at least 7'6" headroom, prefer larger as my two are 17hh.
a friend of mine is thinking of selling his , def takes 17hh as thats what his horse is , its an older wagon but very well maintained & tidy & was resprayed last year , ramp very manageable but no power steering , will a bit below your budget for def , pm me if interested & i'll ask him
Charlton Horseboxes have a 5.5T Renault in at the moment. I pop in regularly to see the 6.5T that they are building for me and I have seen it in there. I think it will give approx. 2 ton payload which will easily carry your two.
