OK I will say that using CO2, or compressed air, may be easier to setup on site. Even that a smaller shop vac would be convenient, and should be 'easier to haul'.
When we were on a site with no 120/240 we had a genset. There was one on the bucket truck, and another could be from the shop. PVC jobs had the hotbox, and/or the blankets, Pipe most times had a power bender, and the 'big' pulls had the tugger. Sometimes it may have given the appearance of a Greenlee site demo.
No, the equipment wasn't used daily, but it was used when it was needed. A sort of bonus was the 'rental' from others who had a need. Ranged from 'favors' to $$$.
