Ever since a Warn let me down by melting the brake and destroying all drive from powering out one length of rope I will never have another electric winch!
Tow trucks use hydraulic winches for a reason.
Logging equipment uses hydraulic winches as well. That said, there are trade offs that many are not comfortable with. Number one is weight, number two is tying that winch in to your power steering pump and the inherent risk of complexity added there. It's all fun and games until you lose a hose and now you're back to armstrong steering, and no winch.
Glad you like yours, but I'll keep my electric winch
Used to sell Smittybilt winches. Roughly a 40% defect rate. 0/10 wouldn't recommend even to my worse enemy. In contrast, the entire time I worked there never once had a Warn brought back. I've seen S/B winches not work and/or break right out of the box. Friends don't let friends buy chinesium.
Maximun pressure is for maximum load, you truck is nowhere near the max load for your 315 70 17 tires, but do what you think best. Yes you will get less rolling resistance with higher pressure but ride quality and tire wear will suffer.
One of my favorite mods on my old Tacoma was a set of Hella triple air horns. Sometimes, you really need to let someone know you’re sharing the road with them. Or maybe you have a 4 legged visitor in camp who needs to vamoose.
