It's harder than oil and flats.... neither generally involve drilling into the frame, and about half the hitch installs do... And some involve relocating the muffler a few inches, and of course, finding someway to hold a hundred pounds of hitch while you bolt it in. And of course, some involve cutting the plastic bumper guard. I won't do it for the last reason, not sure I could do that with good results.
Amen, that third arm comes in handy here.The last one I installed, the hardest part was holding it up while I put in the bolts.
The way I look at it is if it were intended to have a hitch it would have come with one or provisions would be made for one, ie empty holes.Never had to do any of that except drill one hole which did require dropping the tail pipe out of it's mount. . Depends on what you're working on I'm sure.
