Thing is when U see the tanks in action U have no room to haul anything. That being the case wouldn't a simple small 4 cylinder car be a wiser choice since driving a truck like a car is the option. Here is the pictures. Thing to take into consideration is the size ratio needed to capture all the 3600 psi compressed natural gas U need to see a real benefit to ownership of the conversion. If U have a 36 gallon diesel tank U will want a big enough tank to hold enough CNG to fill the diesel tank 2 times, one out and one coming back. I can see a benefit to the guy only driving 25 miles a day with constant refills with a Phill system every evening into a smaller storage tank. But sever limitations to driving range in order to haul his quad. Think $6000 dollars and buy a Platinum edition F150 EB would be a better choice for fun in the sun. Given time and enough CNG supply in ovations and manufactures will off them up at a reasonable price with a designed tank system install inside the frame probably for big rigs. My experience with CNG powered gas engines is it doesn't exactly burn clean in the motor. It isn't like the clean burn of a stove. There is a very nasty residue from it coating everything in the fuel delivery/top end of the motor. There is a lubricant in the CNG that is very nasty.
