Please explain the different M105 variants. What's the difference between an M105A2 and a M105A3?
Thanks

M35A3

The A2 has air over hydraulic brakes and 9X20 NDTs. The A3 has surge brakes, taller truck highway style tires.
The surge brakes on the A3 make it a heavy duty trailer that is possible to carry on the highway with a 1/2 ton pickup while loaded, assuming the surge brakes are in good working order. This A3 also is a six lug, so you can downsize the tires by going back to the 9X20s or even use smaller tires like those on the M1061 trailer.
I have both for sale in the classifieds at this time but like the rare A3 best as it is much more versatile.

Thanks for the answer. So the actual bed is the same? If you were to bob a deuce any M105 would do, since the wheels and breaks aren't used when bobbing, just the bed.

Yup.
