Well. I did a lot of looking to find a canopy for my 2500 long bed 2021 Crew Cab Laramie. Ended up with a Range Rider Vista, made in B.C. I have one of the same model canopy for 26 years and it stood up great. They and ARE were the only two that made a canopy to fit with the high rise option. ARE was 18 weeks to deliver, Range Rider was 4. I like the high rise as it is easier to move around in and I can back my quad into the canopy for security and to keep the snow and mud of it. There are LOTs of canopy makers, the issue is, do they make one for your truck in the configuration you want.
Must have accessories, lights and twin rear door handles. The single rear handles are handy but if you use your truck off road a lot they can bind and be a real beggar to open. Work doors on both side makes getting at stuff much easier without having to crawl in from the back. Twin clamps on the back part of the canopy help hold it in place under torque stress of off roading.
You can see the double work doors, the two handle rear latching system as well as the double clamp system holding the Cap to the bed.
