Whell. After alot of thinking. I have decided to Build the big one for 46" tires. Got 16" rims just a few days ago. They will be build up 16x20" I´m still waiting for my donor to come so I can move the engine over to the big one. The engine broke down so it´s standing outside the garage waiting for an new heart. After that I´ll start to move the axles. The rear axle will back by 10cm and the front axle wil go forward 5cm. That will make a big difference when driving in alot of snow. I´m hoping to get my frineds wlding borrowed soon so I can start the building :) Cheers mates ;)
