I'm looking at this truck on the dealer lot crew cab short box. I know the rear axle makes a difference towing but with a truck camper should I pass this truck up and wait or order a 4.10....I would ...

The lower your gear ratio the harder it is on the transmission during initial take off. The heavier your load the harder it is on the bands and clutches. Couple this with a slight heavy foot and the transmission is not going to last. Heavy foot through gear shifts add to the wear and tear of the TC and the clutches.
I personally would not want 3.73 especially with an increase of the 19.5's dia. My switch from 16's to 19.5's increased the tire dia. by 2inches. I did the math years ago to see what my effective gear ratio was, think it was 3.9X.... I can feel the difference.. during take off and see the rpm difference.
Have a friend that has 3.5x's gears and 19.5's... He has spent a lot of $ on transmission parts and beefing things up to handle this... Think he is on his 4th rebuild. His Cummins is modified and puts out a lot of HP.
