It can be somewhat rewarding. I only do commercial accounts. Hours suck of course. Breakdowns happen, don't care whose make equipment. Welds break, electronics go south. And only happens when there is no where to get fixed, even then -get in line, so ya got to be able to do 98% of your own repairs. Rednecking to get back to shop is a way of life. 1 truck/w plow and a commercial account - you have a lot more guts than sense. ( got insurance? A slip and fall suit will clean you out for life) Always have a back up or at least someone that will cover your tail as sxxx happens. Might want to carry a spare fully charged battery, new electronics on vehicles won't work once voltage drops below 10.5 Volts, Your stock alternator can not keep up with heavy draw from a plow. Batteries last about 2 seasons, fall apart internally from the bouncing and jouncing- again doesn't matter what type or make. I have had Western , Fisher, Blizzard, SnowWay, and now Boss plows. Been at it a long time. Customers don't care when you have equipment problems only that their lot/drive is cleared asap.
