Reverse gear is pretty weak, make the incline very gradual.

That is the only way this truck will go up in reverse pushing a 5000 lb travel trailer,bog down.

"Bogging" in reverse is usually the torque converter clutch partially applying due to a lack of pressure caused by low fluid, filter tube leak, or internal pressure leak from worn sealing rings or damaged piston seals.

This will hurt your mpg a bit I'm sure. Might price a gear swap to some 3.73 or even 4.10. Would probably cure the OD problem and help your bogging in reverse too. I doubt it would take many $5+ gallons of diesel to justify the the swap
