i have had a few 24v granada cosworth transits and they have bags of power on the hills, i use to tow a car trailer behind mine, and i didn't find a hill that slowed it down ever, and would cruise at a ton with the right trailer, on a private road of cause, stick LPG on one of them and you got a real tool, fitting the 24v is easy if your at all handy with the tools, not difficult, pm me for details if you want to go 24v cosworth
