Do lenders impose limits on how much you can get for your first car loan?

I’m going on a road trip in my RV but I want to tow my Crosstrek behind us. Is that possible?

I’m staying at a friend’s house out of town this weekend but there isn’t a public charging station nearby. I’ll have to charge my Prius before heading back—will this spike my friend’s electricity bill?

Are there any good ways to tell if my car needs a new thermostat? The temperature control is all off and a friend of mine said it might be related to the thermostat. I’ve also heard the thermostat helps the engine work, so I’d like to get it fixed as soon as possible if it’s broken.
