gear ratios

The truck is a 1988 R30 Silverado dually four door weighing in at over 6600 lbs. The horsepower will be 375 hp, 400 lbs. torque with a Turbo 400 3 speed. Towing a 30 ft Airstream at 7800 lbs. Would like to change the 4.10 gear ratio in the differential down to 3.54. Is that too much? Opinions please.
