The canopy camper can be removed, but to make a proper seal ribbon sealer or sikaflex must be used (think of removing the roof or glass out of your car). It can totally be done and jack mounts can easily be made for the extrusion skeleton, but you will have a fair bit of time removing, cleaning, installing and sealing every time.
If pulling the camper when not in use is your goal, the Khaya camper will be the way to go. It has jack mounts already installed and installing and removing is as simple as loosening 4 nyloc nuts. Also you can keep all your gear right in the camper when not in use and have a totally stock truck bed in 30 minutes tops.
For your other questions, answers below:
- Will a 3rd-party swing-out tire carrier work with the canopy?
Yes, the rear door on the Canopy Camper does not extend past a normal tailgate.
- Can extra padding or a thicker mattress be added to the bed platform or will that prevent it from closing?
The standard mattress is 3" and you have 3" of space above that so depending on bedding you could add a topper.
- I'm in Utah and a round-trip to New Jersey to have it installed won't work with my work schedule and would be expensive. What other options do I have and are there any distributors nearer to me?
As much as we would love to have you at the shop, I understand haha. Depending on where in Utah you want to give a shout to TAV LLC in ABQ or Juniper Overland in Denver.
Hope this helps and LMK what questions you have.
