Nothing lazy about not wanting to dig a compressor out of the basement. It's the other 100 items we have to move to get to it that makes us lazy.
BTW, if your FIL has a fork truck available that's half the battle with the install. It might be worth checking with the local auto part shops to see if they have tool rental. The ones here in Dallas/Fort Worth do. If so, you could rent the torque wrench. When I bought our fiver I bought a torque wrench to torque the wheel lugs so I used it for the pin box install. Our install required some splicing of wires but nothing too difficult.
Whichever route you go, I think you'll love the Tri Glide once you get in installed. It doesn't take all the bumps and jerking out but we feel it makes a HUGE difference. Well worth the investment, IMO.
