rear end ratio
OK so I feel I am stressing the truck to much in hilly conditions pulling my 5th wheel camper, seems fine out on open road but needs help near the lakes and camp grounds going up those sometimes large...

Changing gears will not reduce the rpms needed to climb a hill. If you need 3000 rpms with your current gears, you will still need 3000 rpms with your 4:56 gears, just maybe in one higher gear.
OP read this post and then read it again.
If you want to go up a hill at a lower RPM it won't happen with a gear change. To do that you will need a bigger displacement engine (think big block because they make their power at a lower RPM) or forced induction like a super or turbocharger.
The new engines as a general rule make their horse power at a lower RPM also.
Sounds like you really want a diesel or even an Ecoboost because they make their horsepower at about half the RPM of a gas engine.
A gear change won't do what "you" want it to do.
I don't totally agree here. What if the current gearing won't quit pull a particular hill at 2000 rpm so it downshifts to 3000 rpm? Maybe 2200 rpm in the original gear would be just fine. It depends if it is close to holding the higher gear.
