Tailgate,
Yes, Earmark has done the great majority of WSBD boats over the past several seasons.
EarmarkMarine.com Install, Supra Gallery shows several dozen Supras but only a few Moombas.
The finished Moomba product looks just like a Supra façade without evidence a sub enclosure has been installed.
I didn’t realize until now that you’re close by. We prebuild the Moomba boxes and brackets plus have construction illustrations on computer file. Stop by the Lewisville Marine facility and take a look.
