Common enough to get one now. Movement, in my eyes, is based off of the go/nogo decision if the current area is tenable to remain in. Anything that makes me have to abandon my home is a serious event, and the additional resilience and carrying capacity of a deuce and a half outweighs arguments. I need to move 3+ people reliably, with a cross country offroad component, with all of our supplies, and a significantly variable fuel avsilability scenario.
The way I see things is that Events either are a temporary situation, where evacuation is needed to protect life and property temporarily, or a permanent situstion requiring evacuation due to total unviability of the area. In either of those cases it works well, unless you own your own equipment as a trucker... then, just load up the truck and possibly trailer and run. Either way, liquid fuels are a very limited and time/money consuming commodity.
The 89 quake shut the entire santa crux county off from the rest of the state of california for about a week. Fuel was at a premium, rationed by stations due to no resupply until the highway slides were cleared, and even then a challenge to get as power was out for the majority of the area. The few stations that did open, ran of genset trailers for only a few pumps. You were better off not burning fuel and just staying in position, living off supplies, until life went back to normal.
Counterpoint, wildfire. This, you know it is coming and the propensity of a total loss event. Prior planning and the space to carry stuff means you can protect your belongings by loading and running, only returning when safe to tally the damage to your real estate. The affected area can be large, and the further you can get, the safer and less hectic things will be. Same with hurricane evac... everything close will fill up quick, the more distance you can put the better since finding a rv park or just any location to hunker down will be easier. Most people won't make a long push so pickings of places to spend the event duration increase significantly the further you can go.
A deuce is also a fun rig to have anyway.
I honestly doubt I will buy one once I have my own truck/trailer, though. More apt to buy/haveinstalled a pintle hitch on the truck and trailer, and small stepdeck + dolly or a heavy equipment trailer to be able to rock some rocky mountain doubles with flat deck capacity for permanent evac. I can make use of either for normal noncommercial utility, anyway.
