I feel ya man. I had a blowout two years ago and it damaged my steel wheel well. I had a small split on the weld that from the vertical to the horizontal pieces. The crack was small and under the bathroom cabinet where it would be very difficult to weld back together. I have a MIG welder but, decided on the redneck fix. I put some eternabond tape on the crack on the inside of the wheel well. It works great and doesn't leak at all. I'm not recommending that you do that. I'm just saying that on my steel well with a small split it worked. Blowouts on RV's suck. That's why I run American made tires -- now.
