Regarding jacks.. I carried my own air/hydraulic bottle jack.... Sort funny story.
Had a guy having a devil of a time getting his 5er centered on the leveling boards so finally I told him get level and will pick it up and center the boards... I can only lift 20 tons.. You can imagine the look Got.
While he leveled I returned to my rig's service side and loaded the jack and compressor..... When I pulled the dragon wagon (A yard and garden wagon. Very handy for many thigns) full of tools back.. He understood my comment.
Story 2 Car.. Porter taking it back to dealer for tire service did not make it. Help on the way but I was there .. he's prepping the factory bumper scissors jack
I have a proper hydraulic floor jack
Also a proper ratchet wrench with the proper size socket.
Easiest "on the road" tire change he ever did.. And this time.. I got to watch.
That poor dealer just lost dang near all their inverntory of new and used cars due to a hail storm (OUCH)
