Now make up the difference with a piece of plate or railroad track, two 1/2" bolts through frame , per 100#.
Now, when you want to go back to T/SA, take the complete weight box out, the spare and jack , plus some gas ,and you're there.
BTW , I had 650 # in my Omega for O/SA, and nobody weighed anything. ;-)

Glad you stated 650 lbs. I thought I was crazy needing 430 total. Small spare and jack is in it already
