I have a Gladiator, and love it. I wave at every Wrangler or Gladiator I see, key word being "see"!! And admit, even for me, it can be difficult to tell if a Wrangler or Gladiator, till they are pretty close. I do get a fair amount of return waves, and a lot initiated by the other driver. Sometimes it seems as if some of the Gladiator drivers don't wave, but I wonder if it's because it's their first Jeep, and are unaware. I think a lot of salesman aren't aware or telling new Jeep owners of the "code"! My first Wrangler, the salesman was a Jeep guy, so he told me about the wave. These days, the dealers seem to hire anyone and have them selling vehicles, that don't know that much about them.
