I can so relate to that conversation, in fact it could have been me and H! My H likes to exaggerate the costs of things, also.
I don't know to me it sounds like a conversation a H and W would have...not? I don't know I've heard that conversation between two many H and W's before so I don't think it's anything to worry about.
Can you just apologize to your H for hanging up on him, that you were concerned about driving the truck. I know I'm the same way if something is wrong with my vehicle. I panic.
I also would be feeling the same way as you in anticipation of H's return this evening. But, I find that if I take responsibility for my part of the exchange then H will soften up and come around quicker.
