Guys up here run Sprinters, Box trucks, utility body (side bins),350 Ford type vans, the newer 'Transit' rigs.
Two have trailers as Tesla touted. Great to leave at a site. One has PV panels with micro inverters for 120 v. A secondary trailer is a tilt bed that he can get his scissor lift, power benders, gang boxes into easy. He also has a stake body trailer that he hauls 'scrap' for the $$$$.
When I had my business, I had Ford 350 vans, a utility body (Enclosed) with side bins, and a 55' Teco bucket w/a utility body.
Bottom line is how big is your budget, anddo you want 'new' or previously owned (certified)??
A good place to scout 'used; is "The Electrical Advertiser"
