Have a 2010 Newmarket Canyon Star 3920, the rear garage door is difficult to open and close. The actual opening/closing operation is not smooth at all. Any suggestions as to what I should look at. How would I check the pneumatic struts in the frame of the door? I see nothing in the track/rails that run vertical and where the struts are located. Any help would be appreciated.
Thanks,
Rick

I have a 2009 3920 and when I bought it, the rear door was not functioning at all. The previous owner had not lubed the hinge at the bottom of the door and when he forced it open, it broke the hinge from the door.
I removed the door and had a stainless steel hinge fabricated. Reinstalled the door and then adjusted the pull on the torsion cylinders. Works fine now.
I would be sure the hinge is lubed and free and then adjust the torsion cylinders in the jamb on each side.

RTD8,
After further inspection it appears that my problem may also be the hinge at the bottom of the door. We also purchased the unit used about 6 months ago. Would you know if there are instructions, pictures, schematics available with removal instructions for the door?
Thanks,
Rick

Not that I know of. I just jumped in and figured it out as I went.

Rick,
Sorry for the short answer earlier. It gets pretty busy here in the morning. It is easy to let the door down on some benches and then remove the cables. You can then unbolt the hinge from the door and the frame. Why don't you try some penetrating oil on the hinge and see if it frees it up. If it is not torn loose as mine was, that may fix the hinge. You can then adjust the torsion cylinders to give more or less lift. I will be more than happy to give you any help I can.

Great advise, Lubing the hinge would be where I would start also.

To add to some links the rear door is discussed in chapter 6 page 11 of this owners guide and here is a brochure also.
I have looked through the bulletins for you coach and found none that apply to your rear door but there are a few for other things you should look at them sometime, all found in COM_NET Link, info in large Newmar Members link I gave you.
Maintenance of the hinges should be on your check list if you drive in winter months on salty roads.

Thanks very much for the owners guide and brochure, very helpful. I now have some leisure reading for couple days. I am going to apply penetrating lubricant to the hinge and hope that helps. You all have been great. Thanks again to all.
