Jman, sorry to take so long to reply. Been busy with the virus thing etc.HI JiminAZ,
Two things:
1. I'm Also in AZ, Tuc, and I was wondering where you got the extender - online or somewhere in AZ?
2. I was dead set on the JEI, but now that I've seen this I'm torn. The JEI, to me, looks much more sturdier, but not seeing either one in person I could be wrong. For the most part I will always have it extended, so the fold up inst that important, but the Siezmic just looks sweet.
I bought mine from someone on Ebay IIRC. They were a little hard to find at the time. Not a big fan of sending my $$ to China but that's what we face these days.
I don't know about the JEI, but the Seizmek is plenty sturdy. I looked at the welds and they are certainly sufficient. I would also say (as a Mechanical Engineer) that the design itself is mechanically stout.
I have loaded a fair amount of stuff on it and nothing has bent or moved or given way. I have hung my full 260 lb weight from it repeatedly testing shocks and such with no noticable effects. Since the side rails are tied back into the bed frame, it just doesn't defect under load.
And I really like how it folds up for storage.
