More than a few moons ago I was offered an opportunity to look at and even drive one of their conversions.
Custom Coach built (builds?) a robust product that is both simple and durable. My initial reaction is that their conversions looked institutional. The ones I have seen possess the styling somewhat similar to the average high school cafeteria. That is not to be treated as an insult, but a recognition that the coach lacks pizzazz, but offers serviceability not provided by any other coach. It will handle spilled food and drinks, dirty shoes, and greasy stains, yet it will clean up easily and handle those problems for years and years. It will hold up to the most abuse of almost any coach out there.
