All trucks came with chrome front bumper but the W/T didn't. They also didn't get emblems, they got stickers. And they only came in a few colors. It was a short lived attempt to make a truck that looked even cheaper than the base level Cheyenne, or maybe more like make the base level truck more appealing by having a truck designated as a W/T with less features. Once the W/T model was dropped, the world started incorrectly (I could be wrong) referring to a base trim truck (Cheyenne) as the W/T. Maybe Chevy did start referring to Cheyennes as the W/T. They are still simply the base level truck, same as always to me. I don't think a Cheyenne Suburban was called a W/T. My '95 Cheyenne shown above came with a vinyl seat. I had it recovered with GM cloth. The '95-up bench seat was contoured and more comfortable than the prior base bench seat.
The '88-'92 Cheyenne grille looked like this
The '92-'93 W/T looked like this
Here's my '95 Cheyenne Suburban
It is similar to the '94-up Cheyenne grille. But other than being darker, the vertical bars were fatter and instead of the thin horizontal with vertical fins in the openings it was a diamond pattern mesh, what I call "speed grille" material
Here is the W/T 1500 sticker for the door emblem and tailgate. Also, I believe there were only W/T 1500s. Base 2500s and 3500s were Cheyennes. And I think they were only long beds
