Roadmaster lists the install time as about 3 hours, so it can't be too bad. They consider "easy" to be 2 hours and Difficult to be 4+. It will undoubtedly take some fumbling to find all the fasteners and bolts for the front fascia, but a handyman-type ought to be able to cope.
But I have to admit that I copped out on my last one, after doing the previous three myself. My Acadia needed to have all the front fascia removed and I've gotten too old and fat to want to deal with it. Had the local pros do it instead.
