The downside with an email is being able to prove that the other person received it. The next problem could be with keeping it intact as originally sent. Email can easily be alter. Hopefully someone will be able to offer some sound feedback to you.
It's not always possible but sometimes using a smart phone to video tape or take pictures of an problem when it's occurring can be worth a thousand words. I was having a microwave oven issue that would only happen when I was using the microwave. I video taped the issue and the tech was able to see what was happening. In my case it was user error.
Great choice for "Living within my means" and camping for one...
