Are there any waxes that would be better for a work truck?

[stephen4785]

I try to keep my work truck clean all the time but it's hard when I have to drive out to well sites every day. Soon as it rains there's mud on everything. Is there a wax that would last longer or should I just stick with Meguiars? And after I wax the truck what should I use to wash the truck that wont strip off the wax. I'm having to wash my truck almost every weekend so I don't think anything is gonna last very long.
Maybe Nick the detail god can help?

For washing, I would use the Meguiars Gold Class Shampoo and Conditioner and waxing the Meguiars NXT 2.0.
