I haven't been in auto sales before, but I can give you a wish list for a salesman.
In San Angelo, you'll definitely be selling trucks. Consider becoming the "truck guy" who knows all of the relevant numbers and comparisons.
Look at an RV forum:

Learn the importance of towing beyond just the tow rating and the irresponsible claims of Toyota's truck commercials:
UVW
GVWR
GCVWR
GRAWR
GFAWR
GVWR - Curb Weight = payload capacity
Know what the listed payload includes. . .
Full tank of gas? (probably)
How many passengers? (generally 1-2 150 lb. passengers)
Which factory items?
Did you subtract dealer installed options? (bed liners, heavier tires, etc.)
For travel trailers, the hitch weight is typically 10% of the trailer weight. For 5th wheel trailers, the hitch weight can be 20-25%. You have to subtract that number from your payload.
Many truck owners are very informed. You'll also be fighting an uphill battle vs. generations of being a Ford, Chevy, or Dodge family. Know what your trucks can
safely and actually do. . . don't just parrot the marketing malarkey.
Just like a well-informed, polite, courteous gun dealer can win friends and gain a great reputation in online forums among enthusiasts, so too can a good truck dealer. That RV forum I linked to has endless discussions of trucks, salespeople, liars, dealers, honest folk, good experiences, bad experiences, etc.
The exact same forum is reached under all of these names (rebadged):
RV.net
OpenRoads
GoodSamClub
TrailerLife
Woodalls
. . . others
Good luck in your new job! The fact that you're already reaching out for advice shows you've got the right attitude to study, learn, and conquer your new profession.
