Soft Bathroom Floor T-2070

[Nitrohorse]

I have a few questions regarding the replacement of the bathroom floor in my Sunline T2070. It appears that my black tank is directly underneath the damaged portion of the floor and I cannot find any obvious water leaks in or near the area. My guess is that condensation caused this damage. If the tongue of my trailer is pointing north, do my "floor joists" or 2 x 2s run east and west? I don't want to cut into the joists if I can help it while removing the rotten OSB. I'm trying to visualize what is on top of the two frame rails that run parallel from the tongue of the trailer back to the bumper. Are there metal cross ribs and then the wooden 2x2 are screw down into them? Secondly, what is the usual method(s) of cutting the flooring out? I have a battery powered small circular saw that I could adjust the depth of the cut, or am I better with one of those oscillating multipurpose tools as sold by Harbor Freight?
Any advice or suggestions are appreciated. This is the first issue I've had with the trailer and I really enjoy owning it.
Thanks in advance.

Hi Nitro,

See here in the FAQ forum under

About 1/2 way down the post is this Subsection

Restoring a Sunline

There are several links in that section with good pics of a rotted floor being taken up showing the floor joists.

Hope this helps and good luck.
