Removing the RVK3500 is pretty easy 1 bolt is all it takes and it is just loosened or tightened not removed takes less than a minute. Having one it works well and am plenty pleased with it but nothing wrong with the puck system either. My truck didn't come with the pucks and I already had an RVK3500 from my previous truck. Made more sense to me to just install the turnoverball than it did to buy a new hitch (turnover ball $400 vs new hitch for pucks 1300, plus the pucks another $4-500.
My neighbors does have them. He went to show it to me was going to remove the puck covers couldn't get them off, nothing a pair of channel locks couldn't deal with easy enough. He as I do use our trucks for other work besides just pulling a trailer once in awhile could be some dirt/rock grit got up in there a bit
