So far, 2 weeks research and consultation are wasted at the fabrication shop and back to drawing board! here is why..... started with the idea to fit a bed roll bar on my Silverado (2011 reg cab) for safety and not for looks, so the after market accessories option was immediately discarded. The first option -naturally- is a rally cars fabrication shop and offering was an FIA compliant cage -in cab- which was also discarded because we'll have to cut through the dash, cancel left and right AC vents and move fuse box, wires etc...., tooo extreme for me, at least for now so, back to bed roll bar fabrication, and suggested that the roll bar will suffice BUT for on road only and "may sink in soft sand and roof front side may collapse" which is actually a valid point; so decided to do an exo cage around the cab and bolted down to the chassis and to be attached to the bed roll bar from top. sounded like a good idea, but as work progressed, the technician today argued that it is not a good idea since the cab cage is fixed on the frame and the bed bar will have 4 points fixed on the body and the truck has a lot of body flix between the can and the bed that will break the bar or the connection points. not so sure, but I tend to agree especially that - in my mind - these trucks has a flexi body twist which gives an advantage on sharp drops on side cresting, ditches etc.. in all cases, I'm doing the bed bar (4 points bolt with X crossing), but my dilemma is about the cab cage because I feel that the set up if not connected to the roll bar with only 4 points with no option for x crossing might be week and risky to may cause more damage that protection! any ideas or suggestions on the matter?
