I’d question the need for that long of an extension. Need to add more info. Presuming long bed truck, that length of extension may be needed for a 10.5-11’ camper but the weight sounds more like a shorter camper. Of course vertical overhang and trailer tongue length are part of the equation too.
That said, 34” extension is a lot for just a straight tube receiver extension without stabilizing chains.
I wouldn’t unilaterally reccomend it without knowing more information. I have used a straight bar extension 12-18” without issue with heavier trailers than you have on a 2” receiver.
You have 2, 2.5 or 3” receiver?
