Frame rail repair
Hey guys need some help/advice. To start off I know the topic says frame rail repair and that a cherokee is a unibody so the entire body is the frame. I just don't know what the rails under a unibody are called. Anyways I saw a crack on the bottom of the rail, on the passenger side in between the stock gas tank skid and the bump stop for the rear axle. The crack was maybe 6 to 8" long. I started poking around at it and now there is a decent size hole. I am going to remove the fuel tank, cut out the bad metal, and weld in new. But I have 2 questions.
First: I did some searching about metal thickness for the rails. Some one on here said the rails are 16ga steel. Is this correct?
Second: I've been tossing around the idea of buying a small travel trailer for camping and this would be the tow vehicle. Should I plate the side/bottom of the rail thats damaged after I fix the rotted out part? Just to make sure its strong enough Or will the 16ga fix be strong enough?
