Truck for a 5000# travel trailer
This is my first post to this forum. I'm sure many of you have seen this type of question posted before, but I'd appreciate your input. My wife and I retired last year and bought a 2011 Gulf Stream...

That is correct info. It doesn't mean your transmission will fail. It means you need to change the fluid more often than normal to protect the transmission. Lugging it in high gear at low rpm's is harder on everything than letting it downshift and run higher rpm's.

Yes, this truck does have the 3.42 rear end.
Regarding the acceptable temperature for transmission fluid, we checked internet references on the road and the guidance that we saw indicated that 180-200 F was a normal operating range and that temperatures above ~220 F would contribute to an accelerated breakdown of the fluid. If the temp gets to 250 F, shut it down. Some references show a temperature duration/rate of breakdown relationship.
