I have had 2 puma’s a 2005 and my current 2014. With my first puma I had no issues other than the lag bolts started to rust after a while .My current trailer is a different story. I had cross member break at a weld,had to replace a torsion bar due to the bolts stretching.although I give credit to BBC for recommending replacing the bolts with grade 8 bolts.i paid to have two coats of gaterhyde on the trailer and still all of the brackets that support the bunks are rusting as are the axles .its has become a yearly task to crawl under the trailer to remove rust and prime and paint those parts.The wiring on the trailer lights looks like it was done by a drunk monkey on crack I have had to rewire both taillights .On a side note my one buddy has to replace three torsion bars on his 2018 Ranger due to the bolts stretching.so again I have to give credit to BBC for advising all owners of that problem
