For sure air bags are your best option. I've got the RideRites with the compressor under the hood and the pressure gauge/inflate/deflate switch mounted under the dash. I love being able to adjust the amount of support I need at any time, including while I'm going down the road. No worries for...
Love my 245/75 R16 E Michelin LTX A/T 2 tires. They're tough, get great traction, last a long time, and provide great fuel economy while having the best acceleration and power. That's the size this truck was designed to perform the best with.
