Got it done
Finally got the toilet done. Ended up having to pay for the welding so it cut into the savings big time but in the end the total was under $400 and it is totaly custom to fit and hang from the frame and the same size as a captians box. So in the end, if you are looking for a one like the partner steel, buy it and save the time. If you enjoy building custom stuff and having it work the way you want it, build it.
