One of the most awful things Ford has to deal with after Stan loses his memory is that Stan very clearly failed to mention that for some reason he’s extremely sensitive to cold and sometimes his fingers and toes will ache a lot when the air gets too chilly—hence why the shack is always a little bit on the warm side. Mabel and Dipper had complained at the beginning of the summer but soon adjusted to the heat, whereas Ford didn’t really notice especially with the basement being several degrees cooler than upstairs and that’s where he spends the majority of his time anyway. But after Stan loses his memory he doesn’t have the tact to not complain about being in pain or sensitive whenever it gets too cold in the house, and Ford realizes with terrible alarm that this is something Stan’s dealt with for a while. A long while.
Once Stan’s memories start filtering back in he begins to complain less about the cold, and Ford gets really suspicious. Eventually after cornering him Stan admits that there was one time, back when he was still living in his car, he didn’t have enough money to afford gas and was stranded for the night—unfortunately it was in the middle of a pretty bad snowstorm and the car was absolutely freezing. Despite Stan’s attempts to get warm it didn’t work out very well and he got a frightening case of frostbite (and was hauled to a hospital the next morning but he sorta skims over those details). Sadly it was bad enough that it ended up being permanently damaging so Stan’s sensitive to the cold now, and the guilt hits Ford like a freight train, because he could have been there for Stan when he needed him, could have invited him to the shack and kept him warm and fed and healthy and not potentially freezing to death
When they go out adventuring on the Stan O War II Ford collaborates with Fiddleford beforehand and the two of them whip up some pretty neat heating devices that Ford pads Stan’s clothing with, because Ford had initially refused to humor the idea of the two of them going into subfreezing temperatures to research anomalies (“Fight monsters, Ford. Say it like you mean it”) because he knew Stan would have a really rough time out there—and Ford never EVER wanted to put Stan through something like that again, even if it was unintentional. So most of the time when things get rough and too cold Ford stays out in the deck to deal with stuff while he buries Stan under piles of blankets in the cabin (because it makes Ford feel better, more so than Stan anyway lmao). Stan’s little heating devices help a LOT and Ford always makes sure that Stan tells him whenever he’s feeling too cold (and by now Stan trusts him enough to do so and knows that if he tries to brush it off Ford will get really upset with him).
Mabel sends them boxes and BOXES of hot chocolate packages and hand/knitted scarves, sweaters, mittens and socks. The really thick warm kind lol. Every once in a while Dipper will toss in a recipe for a hot meal, along with a few suggestions to spice up Stan’s morning coffee, and some general tips and tricks about staying warm in the arctic (Stan had originally questioned how Dipper knew all this, to which his nephew sheepishly told him “Hours and hours of research”. Stan was extremely touched). Soos secretly informs Ford of Stan’s telling signs when the lingering effects of frostbite are bothering him, so he can be prepared. Ford hovers incessantly like a mother hen and eventually Stan has to lecture him about personal space—but there is never an incident where Stan gets too cold again, and Ford and the kids start keeping records of it. (It’s a little over the top, but Stan appreciates it anyway.)
