Welcome RV noobs,
There are many strange terms on RV forums. You'll eventually figure them out. Here are some off the top of my head. Some terms are nautical in nature like with boats. I hope I understood these properly this past 10 years.
coach = motor home
shore power = electric via your thick extension cord from a power pole
boondocking = camping without any hook-up to electric, water, or sewer
galley = kitchen
toad = a vehicle that is "towed" behind the motor home
tv = tow vehicle, and a television too
dw = darling wife
dh = darling husband
tt = travel trailer
5th = 5th wheel (the kind of trailer that is towed from inside the bed of a pickup truck)
super C = a class C motor home like you have, but the chassis is a real truck instead of a van
B+ = a class C motor home, but without the overhead bed, just an aerodynamic cap like I own
