Good job!! Having good tools is a plus, but knowing which tools to bring comes from experience (and a bit of luck). Then you need not bring the whole roll-around.
But I did cringe when I saw your legs out underneath the MH, with the levellers extended and no jack stands! I could see myself doing it... but it is not safe.
Same as not always killing live circuits before working on them... too lazy to get proper eyewear when working on the batteries... using a boxcutter as a "saw" and cutting my finger open.... did this 2 weeks ago.
But good job, well done and I hope the claim goes through effortlessly.
