My ladder rack on my 845 works for various bikes that I have used. I can open the camper door with no problem.
If for whatever reason you need to use a bike rack and tow . You need to be careful , it's possible to damage the trailer if you turn too tight .
I use this from CWsomeone made a fork mounted mod for a rear ladder. If I can find it , ill post it . It uses a fork mount like the one shown here .
