Asphalt storage pad

I'm extending my driveway (12' wide) by 17 feet so I can park my 33' Forest River 5th wheel on it for a few days before and after our trips. We have an offsite storage facility for long-term storage. The dry weight is 10,000 pounds, axle dry weight is 8,000 pounds, hitch weight 2,000 pounds. It is a dual axle. When parked, we will have 2x12's (2' long) under the rear stabilizers and under the front jacks. I'm getting quotes for the asphalt. One contractor says 4" crush run and 2-1/2" hot mix will do the job. The other contractor says 6" crush run and 3" hot mix and is using the "better safe than sorry" argument. Where can I get an objective opinion on how thick the asphalt needs to be?

    The base should be CA6, road pack and it should BE packed.
    Have you considered and/or priced concrete ?

    Just like tow vehicles .... bigger is better. You'll never be sorry for going with the thicker pad. If you go thinner and it begins to crumble in a couple years, you'll be VERY disappointed. Do it right the first time and you'll have no regrets later.
