You can certainly get automatic transmission horse boxes - we've had two - a large Renault Dodge and a smaller 3.5 tonner. Both were excellent to drive both up hill and down dales. No problem whatsoever with either of them. Would suggest that if you're looking for a little one, see about buying a cab/chassis and get a body put onto it. In all the years of having automatic lorries, we never spent a penny on mechanics of them.
Yeah ,, You Can Do But They Are Quiet Rare To Get , . unless you go for the £200.000 big scania's..! My Friend has got a little automatic lorry for sale..! x
