Go for it. Forest thing is we independence need to push for the "Right to Repair Act". As far as getting around the corporate crony capitalists theres a few solutions. First of all find a brand that doesn't lock out and restrict the private tech so much and push your customers to buy those machines. Some pf the more accessible brands that don't need a laptop every time the operator sneezes are Crown, Toyota which allow most diagnostics to be done from the dash. The worst one out there are companies like Jungheinrich and I tell my customers to retire them early and get a Crown instead. They usually see ROI in short time in decreased service costs. Then there are some other in between companies where good friends can lend you a manual or you can get them from overseas where right to repair act has already been passed (talk to your own lawyer about the legality).
