Welcome to the site tldcod. The Max IV is a great machine and the dually kit is way cool. You have a few options to make your tub right. You could call RI and get a blemished one from Matt O. He has some blemished tubs I know he would rather sell than move with the factory. Plastic welding the hole closed or a patch in it would be your other option. I have done this before, and it is a tedious process, but not very difficult. Patience and not over working one section by staying there too long is key. I have scrap hdpe from a max lower laying around if you want to give it a try. Pm me if your interested.
l like to buy stuff and no I don't do payments!
