One of the reasons I bought it was as a base for my '86 Tischer.
I have to decide which to sell the '86 or the '79.
Have not tried the Tischer on the pickup yet. Having a syncro improves behaviour in cross winds or at least that was what we found when we had a new Tristar (petrol) and a Tischer DOKA demountable. Against that you loose payload.
Jake is right it is a good vehicle. If I keep it it will have to have an engine upgrade as soon as I can affod it.
