I have a Solera 24R and purchased a Swagman XC Tow bike rack that holds 2 bikes. You can see it on Camping World web site item # 49402.
After you get to the camp site and remove the bikes you pull a pin and the vertical support lays down flat and gives you more than enough room to extend the slide. I also had to get a tow bar extension to keep the handle bars away from the rear of the coach. Shop around for best price and do not forget to lower the vertical support before operating slide out. It works great.
