Does Grand Designs use the same size and grade wet bolts on all of it's trailers?
The wet bolts are supposed to be grade 5 according to MORryde. BUT, grade 5 bolts have three "tic" marks on the head, my original wet bolts do not have the "tic" marks. So, there is no telling what grade they are. This is only my theory and I'm not saying this is what happened but, I think GD had a shortage of grade 5 bolts during covid and used cheaper bolts so they could keep producing RV's. Now the customer is paying for it. Again - that is just a theory.
