When looking into the AL-K0 8490 references an AL-K0 hub for a 3,500 pound axle with a 10 x 2-1/4 inch drum and a 5 on 4-1/2 inch bolt pattern. There are two sets of brakes I would recommend looking at the will work for your popup camper. The Electric Trailer Brake Kit For Self Adjusting Brakes # AKEBRK-35-SA or The Electric Trailer Brake Kit For Manual Adjust # AKEBRK-35.

If you would also like to replace the hubs on your axle, as long as your existing AL-K0 hub uses an # L68149 inner bearing and a # L44649 outer bearing, the trailer hub and drum assembly # AKHD-545-35-K has a 5 of 4-1/2 inch bolt pattern that would work for you. I will attach an article showing you how to measure your hubs for the correct bolt pattern.

I attached a review video link below.
