Mewtric! I wuz dragged up Imperial! :cool2: Though in the good old days I was towing a Rice Farmers Hunt trailer 18 cwt unladen, with two big horses, say another Imperial ton, with a 240 Volvo 2.3 auto estate. I was on the M4 (Luckly) Thought I was making god time but transmission was getting hot. Then looked at the speedo 95mph!! Learnt an important lesson, watch speed when towing!
