It certainly is what cambering is. Do some googling as I did. There is more than one way to do it. But I found articles of some really big semi type stuff being cambered by welding. In addition at one time, Northwoods RV had a picture of welds on one of their frames stating it was cambering for more strength. I also toured the Palomino Sabre factory back in 2010 when I bought my Sabre. I took a lot of pics. One of them shows the cambering welds. I have that pic, but I haven't posted a pic in so long, I forgot how to do it
And welding certainly does change the way a length of steel feels.
I tried it and felt it it myself. If you still don't believe me.... Break out a welder and see for yourself.
Flatbed semi's, the beams are often cambered. If you see them running empty, the curve is easy to see but they are built for many tons of load. Far different from your average travel trailer.
I've seen a fair number of travel trailer frames and not seen cambering...at least not enough to visually see anything. They will sometimes reinforce where the axles connect but that's different from cambering.
I suspect what you are confusing is looking at the strength of flat sheets vs an I or box beam working together but that's different from cambering.
