BryanValRox,
Not sure you would need one of the above if your surge protector s worth anything. Mine tells me right away if the electric is not perfect.
No need for diplicate devices to tell you the same thing.
Flyer, understand your point 100%. The method to my madness is that we get to the site and get either pulled in or backed in. Then, the first tote inside my basement door contains my wheel chocks and this tester. After chocking the wheels, the tester gets plugged into the pedestal for validation of the service. This way I can validate the electrical before dragging my cord or anything else out for that matter. If all is well at that point, we start to unhook and set up.
Also in our case we have an onboard surge protector, so I would not be able to validate before plugging the cord in.
I was just sharing what works for me and offering a suggestion for consideration.
One thing is clear , we all have different reasons for what we do, and there is no one size fits all solution.
Hope you have some nice trips scheduled for this season.
