A New Way Of Truckin'

I was super surprised to come across this bit of information recently.  Seems that the conversions get more impressive each year.  I am so glad people are really getting into this area of engineering and production so much nowadays.
Indiana-based ATC Mobility claims to build a high-quality, more versatile and desirable converted vehicle for the 1.7 million Americans who are confined to wheelchairs. Engineered to last, ATC’s patent pending lift system works in a variety of trucks and SUVs and is sold at dealer locations throughout the U.S and Canada.
Their mission is to supply customers an exceptional product that provides a truly unique life changing experience through mobility with style.  ATC conversions are developed through a team effort that ensures the highest quality design for manufacturing, efficient assembly processes and competitive costs and services.

They currently convert the following 2008-2013 GM trucks: Chevy Silverado 1500 or 2500 and the GMC 1500 or 2500 as well as Suburbans,Yukon XL, and Cadillac Escalade ESV.  And they'll do either a driver or passenger side conversion for you.  Most wheelchairs will fit in their 2 wheel drive models, however 4 wheel drive models have some limitations so you'll need to discuss that with them early in your inquiry.
They have a custom shop that can put a lift in other makes and models, however prices of conversions can be 3 times their production price. Also, build times are 3 times longer since many parts have to be custom made.  But if that's what you're interested in and you have the cash, they'll be glad to work with you and will consider the feasibility and get you a quote.
