The problem with the 2015+ Colorado/Canyon is that the antenna assembly provides GPS/XM/Onstar/AM and FM signals. The only ones of those I care about are GPS and XM (for traffic), so I would need some sort of way to relocate the GPS and XM antennas to the top of the GoFast near the front hinge with a selection switch to switch between the 2 sources, or maybe in the bay where the windshield wipers are like I did in my F350 with truck camper which could be permanent. I realize this is not really a problem with the GoFast design as any type of camper or cargo up there would block it, but it's something I would need to figure out. The only post I could find about someone doing that was here: http://coloradofans.com/forums/201-2nd-gen-electronics-audio-lighting/314386-xm-cell-data-gps-am-fm-antenna-anatomy.html
The part I am talking about removing and/or relocating is the tip. Retaining the smaller base is necessary as you stated. The tip is only for radio. The xm/onstar etc functionality is retained in the base so by removing the tip you gain a lot of clearance without removing a lot of functionality. The reason the base isn't a shark fin is cause our trucks have the radio integrated into it. If we had a radio antenna on the hood like the 2018 Silverado then it would be a shark fin. As is though if you were able to relocate the radio antenna then you would retain all functions. Would be cool if you could just plug in the camper to that base and it act as the antenna since it's a giant piece of metal anyways.

Right, removing the antenna gives you clearance, but good luck getting XM or GPS through an obstacle like a popup camper. The Onstar/cell would be just fine and relocating the antenna would be relatively easy, but in my experience XM and GPS are very sensitive to any type of obstacle since they both need line-of-site to the satellites more than 12,000 miles away.
I wanted to organize some of the information Wiley has shared, so I created a FAQ on the main TacomaWorld thread about the GFC Platform. I tried copying it here, but the links don't translate, and I don't feel like cranking through all of that again.

I have a 6.5' f150. Would the XL version fit my bed size? What dimensions exactly change in the XL version?
Thanks
Hi,
I'm the designer and a partner in GFC so I should be able to answer any questions. The tube structure is the frame for the lower portion of the camper. The frame will be wrapped in either canvas (like a can-bak or softtopper) with sides that roll up, or in aluminum panels. There will be an insulated liner option for the upper and lower not long after we start shipping. For the aluminum paneled version there will be a rear glass window and on the soft side version there will be a zip open plastic window.
Weight on the soft-sided version (upper and lower combined) will be under 200 lbs, and about 245 for the hard-sided model.
While technically you could separate the two, we'll initially only be selling them as a unit. That said, we will eventually be offering the popup portion as a stand-alone RTT with a solid floor, or as a kit that could be integrated into a van top. We will also be selling the lower as a stand-alone topper without the popup.
