Since you did not specify what model you are getting, all I can say that the 36 Series has the TrailAir L-05 option and the TriGlide add on option if you specifically asked for it. Its at least a few hundred bucks more so you should know. You can call Justin Day at Cedar Creek, 260-593-2598 and ask him but your dealer should be your first point of contact.
What kind of hitch is not compatible with the TriGlide other than auto sliders?
The recipe for perpetual ignorance is:
Be satisfied with your opinions
and content with your knowledge.
