Fuel 352 Toyhauler Rear Bunk Beds

we have a new 2019 Fuel 352 Toyhauler and I'm looking to replace the lower rear queen bunk/convertible benches to just a bunk like the top. Are these bunks the HappiJac bunks? I found a new upper HappiJac queen bunk dealer take out but it came out of a Keystone Carbon toyhauler. I didn't know if all the HappiJac's if they're a queen size are the same.

Thanks,
John
