Very much agree. Don't be won over by nice bits such as lovely living - it is the chassis etc that you need to get looked at and if you get a good lorry/horsebox mechanic they will know what to look for on a particular type or model of lorry. Also sounds silly but make sure you are going to be happy driving it. Had one lorry a few years back and it was only when I got it home I realised quite how big it was.....(a 7.5 tonne one but a long 7.5 tonne one if you know what I mean!)
Go in working clothes so you can have a good poke about then if you like the look of it take a mecanic to look it over before parting with your hard earned cash.... oh and you need to know how much it weighs so you know it can do what you want.. if its over 3.5 tonne the vendors should have the brake test sheet which will give you a guide to the weight otherwise you should ask for it to be weighed (costs about £5 )look up public weigbridges for the nearest, good luck....
Ah yes, see the paperwork re. the pay load (how much weight you can legally carry). Mine was 7.5 tonne, but only had a payload of 1.8 tonne - considering it was stalled to carry four horses...
mechanic!! plus which its worth having a good chat with the guy who will look at your lorry (maybe the person who will be maintaining it for you?) - I was given a lot of info when I went out looking, so that I was able to pick out something reasonable before moving to the "vetting" stage.
I would say go and view by yourself and then only take a mechanic with you just prior to giving over money, it can save a lot of money in mechanics fees.
Regarding the payload issue, the only accurate way of getting the true payload figure is weighbridge, the plate in the cab, unless it was a horsebox from brand new, will show an unladen weight of the vehicle in it first life as a normal lorry and will normally be grossly innacurate and the brake test certificate are known to be wildly innacurate, being sometimes 300kg different for the same truck on different days.
Let me know what types you are looking at and I may be able to give you a few places to look at.
Things to remember powerfull enough engine with good services history, make sure engine runs smooth and leak free.
Next look at chasis is it rust free???
Next horse area what's floor made of??? Is it leak free, how is it construction, condition of ramp next??? any rust???
Then last what's living like???
and IMO whats colour and paint work like...
DON'T get blown over by shiney PAINT as it can give people rose tinted glasses, rememeber it's got to be reliable, NOT shiney
if you like, then, invest in getting a knowledge truck man out........
Simple answer, get it inspected!, If you take a mechanic with you and its a heap, then you have wasted everybodys time.
Go and view the truck, and if your gut feeling is good, leave a £100 deposit and get a professional inspection done by a prefessional inspection service like Horseboxworld ( www.horseboxworld.com ). Better to loose £100 than £1000's in repairs.
You would not spend £0000's on a horsewith a vet certificate, so why would you not do the same with a horsebox!.
