Are Dually Extension Brackets Unsafe?

I spend 1/2 of my life in 4-seasons and common knowledge is that narrow tires cut better in fresh snow, so dually will be in disadvantage as you have to push twice as wide path, but when come to black ice, I don't think size matters, where quality of rubber plays main role.
I do have hinged jacks and have been camping off the truck just fine.
Noticed some problems with floor separation as my camper had dryrot damage, but after fixing that no more problems.
My hinges locks in the position, so give no play, while wider footing should add to stability.
