Where are you - I am in Seattle. I think we need to talk. I am in planning / stuffing piggy bank with pennies to convert a 56 Chev 1/2 T.
Progress so far
Have truck pretty good shape
Have motor 50 HP Leeson 3600 RPM 3 phase. cost 229 at Boeing Surplus
Next effort set up a shop more than likely in South Park.
Inverter Hitachi SJ 300 - cost about 4400.
Batteries more than likely wet lead acid.
Keep an eye on Boeing Surplus for motors yesterday 40 HP 1800 RPM went for 200 - so far VFDs are all 480 and too small.
