I installed one on a UHaul. It came with a narrow panel about a foot wide centered behind a vent. I mounted the larger panel to the original bracket and let it hang out in all 4 directions.

If I was starting from scratch, I think I'd use four aluminum or stainless steel Z brackets mounted on the corners and long enough to allow the center of the panel to clear the roof center. Alternatively, you could get a pair of narrow panels and mount them on either side of the center, but they wouldn't be in the same plane and that may affect their efficiency somewhat.

If the panel is well mounted, wind should not be an issue as it is parallel to the ground.

A late reply to this, but there are a few pictures in this thread of solar panel mounts on Trilliums:

My panel is half way down in the thread, it uses Z brackets similar to the ones posted above.

Also, if you don't want to drill into the roof, I was thinking of using these VHB brackets for a high voltage panel next year:

Hi, I installed a fairly large 40 watt solar panel on the roof of my Trillium 4500 about 18 months ago. My solar panel has an aluminum frame as it was previously used in marine buoys before I got it. I made 4 “L” brackets from aluminum angle pieces each about 8 inches long an about an inch and a half on each arm, and stuck them onto the roof, then attached the solar panel to the brackets with sheet metal screws. This has 3 advantages: (1) it provides a small airspace between the panel and the roof for ventilation; (2) it eliminates worries about the curve of the roof; and (3) it means I don’t have to make holes in the roof. The setup is removable if I ever want to because the panel is held onto the brackets with screws. I used 3M #4950 VHB tape to hold the brackets onto the roof. I secured the wire running on the trailer roof and down the front to the battery box (where my solar controller is installed right next to the battery) with a different kind of VHB tape, the “No More Nails” construction adhesive tape. The system has worked great (pictures attached).

I have been very pleased with the way the VHB tape holds, and would definitely use it again if we decide to install another panel behind the roof vent.

Rick, did you find the 3M #4950 VHB tape locally or did you have to order it online?

I ordered it from National Hardware Sales Ltd. sales@nhsmedia.com 905-513-3994 in Toronto back in spring 2011. I could not find it in Alberta. Cost including shipping was $73 for a 36 yard roll of ˝ inch tape, which I have since used on several other projects. I received it in a few days.

I haven't done it yet but I'm going to install my panels on hinges on the kitchen side and back side. They'll be used as awnings when up, and locked vertically in the down position. I'll make some vinyl covers for when parked (no temptations, please). When traveling I could take the covers off and be charging.
Anyway, that's my plan.... I'll start a thread when I get to it (probably before my 5 day Thanksgiving trip).

I don't have a Trillium but I did install an 80w panel on my Cloud. I found that it would not mount flat because of the curve of the roof so I had to become inventive with the materials I had available. Check out the pictures in my profile to see what I came up with. Good luck with your install.
