I did my class-III myself in about 45 minutes total, taking my time, cleaning all surfaces and the bolt holes with a brush/WD-40, and torquing everything to specification with a long 3/8" torque wrench. My wife helped by getting the bolts started while I muscled the hitch up in place (it's a good 60 lbs so not for the faint of heart...using arms and knees to hold it in place helped a lot). $220 for install is outrageous. I believe I backed the RAV4 on to my ramps that I picked up from chinamart.The most time consuming part was getting the exhaust pipe un-pinned from the hanger (exhaust pipe was in the way on the 2015). Will want to spray some dry lube on the hanger pin to make sliding it off easier.
