Maverick Tremor GFC owner here since July ‘24. I throughly enjoy the Camper version. for those wondering about MPG I choose to put regular unleaded (Top Tier) in and have been getting 23.8 MPG combined (city, hwy, off-road), consistently. I recently just put a Rough Country 270 degree awning on and still haven’t seen any decrease MPG. The awning does sit pretty low, I’m 5’11” but if you buy the enclosure attachment it includes extra telescoping poles (3) so you have 4 total that you can raise the awning up at least an inch or so.

For those worried about water seeping in I have noticed a slight stream of water after washing coming in from the cab-side of the topper but never into the RTT (Roof Top Tent).
For those worried about the antenna I did put a Stubby on. At first the installers were thinking it still might rub on the roof. They shaved it down slightly and put a silicone cover and I’m still able to get radio reception. I mostly use CarPlay but still find it important to have radio capabilities for leisure or emergency information.
Cheers.
