Yea it is.
Out of all the manufactured for sale frame connectors I have seen, the ones that weld to the floor have to be pretty much the best for strength.
I have also seen home made ones that protrude up into the cabin and are welded to the floor along thier length.
I am sure they are just as strong if not more so, but a lot of frikin work.
All those 1 inch tube bolt in style are pretend in my own opinion.
I'm sure they help, but not near what you can do home made.
My own are .085 wall 2x3 tubes laying flat up against the floor but not welded to the floor.
You will also notice that mine don't just butt up to the cross member section, but are also welded under it tying into the frontrunning section.
There have been a lot of ugrades since these pics, so forgive the crappy exhaust.
