What size Cab over truck do I need?

[fastcutter]

What size of cab over truck do I need to haul 4 Grasshopper,2 backpacks,6 Trimmers? Have you ever seen a Landscaper Body witha gooseneck hook up on it? I like to see if can get one to pull a 31' gooseneck with a TS 90 Newholland tractor witha cab, and a 10' bushhog?

Thanks for your time... :help:

Mack MR-600 with a 300HP and maxidyne 5 speed. They will run over 500,000 miles with little to no wrench work. You can go single axle if you want, but I would go tandem. Don't waste your money on torqueless mid sized and light duty trucks.
