Depends on mud....Im from very muddy kind of place originally every one had 4wd, another thing is nasty roads when you have to go steep uphill at the same time. I avoid mud with my 2wd (and mostly avoid entire moonsoon season where it happens) but when I end up in potentially muddy area I just rely on my big food and water supplues that can carry me "until it all dries out" in case. With camping getting overrun its nice to have extra capacity due to 4wd to go beyond.
When I had a little 2wd truck I'd go fast in sand and rarely get stuck. I'd keep the tires on the low end of ok for driving on the highway, and leave them there, unless I was taking a long highway trip. Airing down was how I'd get out of being stuck in sand, and it never failed to work.
I had two Amazon pumps burn down on me earlier, one Stanley pump/jump starter combo too, so I'm back to using old Slime pump found in walmarts and auto parts stores, it proved to be more durable. I do inflate fires to spec 80 psi. Every time I drive its a long highway trip to a new camping spot, so keep ut to spec to keep tire longevity and get expected gas milage. Pump adds about 12 psi per 10 mins of pumping on each of those good sized tires, after that 20 mins cooldown, imagine pumping deflated 6 to spec. You can push the pump but eventually it will burn when you need it the most.
