Sunline Coach Co., Denver, Pa., has begun building what the company believes is the first production-line travel trailer designed specifically for people with disabilities. Designed with the assistance of wheel-chair athlete Mike King, the Sunline Advancer 20 features a standard ramp or optional lift, 42-inch-wide entrance door, roll-in shower, portable table to create a barrier-free, open floorplan, strategically placed assist bars and lowered light switches and other key controls. Available in one 20-foot floorplan for a base retail price in the high $20,000s, Advancer 20 initially is being sold by 10 Sunline dealers. The builder is training retail employees on how to sell the vehicle. “There needs to be an understanding about how to address the customers, what their needs are and what accessories can be put in the trailer,” said President Joe Bucara. “It is our intention for Advancer 20 to be usable in a campground. We had to understand how to get the trailer designed so that it is significantly responsive to a larger segment of the market for people with disabilities.”
