Hi There!. To the original poster. I'm not sure if you solved your issue those years ago, but I ran into the same product just yesterday.  My resolution was as follows:

1) Modify /Themes/<ThemeName>Views/Shared/_CurrentPageClass.cshtml - Add logic to check for your custom controller action so it returns the class customer-pages-body for the body tag

 var isMyCustomPage = controllerName.Equals("mycustomcontroller", StringComparison.InvariantCultureIgnoreCase) && actionName.Equals("mycustomaction", StringComparison.InvariantCultureIgnoreCase);


if (isAccountPage || isOrderListPage || isReturnRequest || isBackInStockSubscriptions || isRewardPoints || isForumSubscriptions || isMyCustomPage)
    {
        <text>customer-pages-body</text>
        return;
    }

2) - Modify /Themes/<ThemeName>Views/Shared/_ColumnsTwo.cshtml - Add logic to check for your custom controller action and add it to the logic flow for 'isCustomerAccountPage'

   var isMyCustomPage = currentController.Equals("mycustomcontroller", StringComparison.InvariantCultureIgnoreCase) && currentAction.Equals("mycustomaction", StringComparison.InvariantCultureIgnoreCase);



    isCustomerAccountPage = isCustomerAccountPage || isOrderListPage || isReturnRequest || isBackInStockSubscriptions || isRewardPoints || isForumSubscriptions || isMyProductReviews || isVendorInfo || isHelpDeskPage || isMyCustomPage;

    if (isCustomerAccountPage ||
        currentController.Equals("order", StringComparison.InvariantCultureIgnoreCase) ||
        currentController.Equals("blog", StringComparison.InvariantCultureIgnoreCase) ||
        currentController.Equals("richblog", StringComparison.InvariantCultureIgnoreCase) ||
        currentController.Equals("richblogsearch", StringComparison.InvariantCultureIgnoreCase) ||
        (currentController.Equals("catalog", StringComparison.InvariantCultureIgnoreCase) &&
        currentAction.Equals("producttagsall", StringComparison.InvariantCultureIgnoreCase)))
    {
        isOneColumn = false;
    }

Cheers
