Quick question...do you guys think the trailer as is, is sturdy enough as a non off-road trailer??
No. The way your trailer is constructed the bulk of your load is biased to in front of the axle and stops right where your tongue connects to the frame, and you have a fairly long span from there to the ball connection on your hitch. In essence it's just begging to fold in half. Even on the highway you're placing trmendous load on that connection point.
I would not run it. It could be a slow failure or a catasrophic failure but I would have little confidence that it would not fail. If it were me I'd cut it loose and run new tongue legs underneath the existing frame structure back at least two crossmembers.
