Thanks Gene in NE for the response. I posted this topic in the c class motorhomes and received a response from CharlesOK. Turns out these slideouts are made by BAL. I found their web site and downloaded information from them. Decided to purchase the 252DS. We pick it up on Friday. http://www.norcoind.com/bal/products/oem/accuslide/index.htm
There is only one dealer in Ontario for Trail-lite. Only the Ford chassis is available in Canada, now. The Holday Ramblers are not sold in Ontario. Wish we didn't have to pay a 14% sales tax.
I shall keep reading this site to learn more aout the upkeep of this machine.
