If roads are clear like Jerry's picture it's not too bad....black ice or equal is not fun.
Down hill on compact snow is not fun either. But with chains on truck and trailer is not an issue. I've come down some 10-15% grades that way with just one hand on the wheel doing 15-20 mph.
Uphill is not too bad, until you lose traction. Yes that can happen with 4wd even.
I prefer chain chains I've cables unless on steer axle. The diamond chains are better and easier yet to install. Get the non SAE for the truck, best for trailer. But the SAE ones work on the trailer. SAE is low clearance, 3.5mm chain, non SAE is 4.5 mm chain size.
