I purchased the EC30W last summer and have just now got around to installing it. I put it in last weekend but have not thoroughly tested it yet. We wanted one for backup in case we lose shore power as we always camp with our Boston Terriers and French Bulldog.
I could not find one anywhere in stock online but then remembered the Souteastern Onan repair center is within two miles of me. It did not come up in their system until I showed her the web page from the Onan site with the part number. She was able to find it at another location and have it shipped in.
