A couple of thoughts off the top of my head. Obviuosly, an unsecured RO/DI dolly or cart would be a deadly projectile in an accident, especially in a van. I think you would be looking at liability issues if you sold products and or systems that claimed to be “safe” in an accident. No matter how well you design a mounting system, **** happens. Who takes the resposibility if your system wasn’t installed properly? What if it was installed properly, and still failed?
What about insurance? I am not an expert, but I would think that somewhere between your vehicle insurance and your business insurance, your equipment might be covered. So, ignoring the safety factors, and looking at it from a strictly cost point of view, would I want to pay extra equipment costs, to try to protect equipment thats already covered?
You would have to be crazy to install a system in a vehicle without being sure it was absolutely safe, and you would have to be even crazier to drive it
I drove an E350 with a 250gal tank in the back for about 10 years, the force that it put on the van was incredible when it was 3/4 full
If you are having a tank installed then make sure it’s baffled, Transmissions are expensive:D
I thing the safety factor should be top priority. I would find it a great service for the heavy duty steel bands that are used to mount water tanks included in all sales of water tanks.
