My job is not quite that good, but still a nice enjoyable (not too stressful) job. I am the delivery coordinator for an RV dealer. Which includes doing the walk thrus. I am considered a tech, and do some tech work when there are no sold get readys/walk thrus waiting.
Seriously though. Performing the walk thrus is the best job I ever had. Yes there are some nitpickers that expect a 20 yr old unit to be better than a new one, but basically most folks understand that the walk thru guy has no power to spend money on a unit. If they are not satisfied, I simply get the sales person to deal with money spending issues. Its the people I meet that makes this job the best job on the planet.
