a quick update for everyone. Finished up pulling the misc pieces off the trailer today and found the rims I was looking for in the back of the shop. It looks like they will fit just fine. They were the correct bolt pattern after all. 5 on 4.5 like most trailers. The brakes are on their way and should be in stock with my northern dealer sometime next week. Will hold off on the brake lines until we get the rest of the trailer loaded up and balanced. That way I know how much to take off the front tongue. The disk brakes use a conventional style master cylinder setup for the hitch point, and I don't want to have to do the brake lines in stainless twice.
I am going to pull the front cross bar that attached to the trailer tongue as far forward as possible.
I want to make sure the firrebox does not hang out the back of the trailer rails when done. Snapped a quick picture of the trailer up on the stands with the new/used rims in place.
If the weather holds for tomorrow I will start stripping the tank down and getting the brackets off. This way we can rotate the tank over and put the vents pn the bottom. I am going to use the pipe openings as my drip and drain locations. If this goes well we will start getting the tank mocked up into location with the firebox. Hopefully the rain and snow holds for one more day.
