I would like some advice from people in the snow plowing biz. I have a 1990 f-150 6cyl.standard shift,and a 97 f-150 .I have gathered up some decent plowing accounts and need to make a decision on which truck to put plow on.the 97 is used for lawncare biz as well.the 90 is parked but in real nice shape,it has 137,000 miles,other option trade up to a f-250 or 350,hate to take on the bigger payment of new one.I have been leaning towards the 90 for plow only truck but do not know how it would hold up to the Maine winters. any advice would be appreciated.
