Mini draws about 40watts at peak usage (20watts at idle) so in that application it should work really well. If you could have it somewhere that you could manually wipe the snow off it that would help too.
Yeah you could get your new mini and activate it. Deactivate your old starlink dish. Should all be on the same account. The plans for the mini are $50 for 50GB or $180 for unlimited.
We have 2 tandem grain trucks with 10 speed autos. One with a clutch, one without. I prefer the one with the clutch especially for backing up on uneven ground.
Go on my phone and crank the heat 5 min before I leave. It takes probably 1min for the air to get hot. My car now has a heat pump which is more efficient. My old car had resistive heating and it got hot very fast but used more power to heat.
