I can tell you from first hand experience that the Ready Welder portable system was a life savor for me on my last Rubicon Run trip. I ripped my lower control arm mount clean off the front axle (which is a huge weak point on the stock suspension) in the middle of Caddy hill.
The guys from the Jeep Jamboree USA had a new Ready Welder system just ordered along with 2 yellow top Optima Batteries. With in 30 minutes they had me back on the trail with no issues from caddy hill to the end of the trail.
Since then I have purchaced one of the Ready Welder systems and had a custom dual battery tray built for 2 Optima Yellow Top Batteries mounted in the back of my Jeep.
