Thanks for asking this question. 2018 24.1. I'll definitely check that method out especially the mention of looking for the yellow cap. Some mention it is easier to access from under the right passenger fold down dash area where you would find the battery. We will both have to do this some day. The engine cover dog house is a pain but understand if you live in the south the heat from an uninsulated dog house is miserable but there are things that can be done to mitigate this.
