Hey im looking into increasing my fuel capacity im running 2 75gal tanks right now otr 53ft flatbed. my goal is to move up to 2 100gal or 2 135gal tanks. im wondering if this is worth a diy headache or should I find a shop. also aside from the tanks will I need to purchase any other items, tools, etc. All useful advise is appreciated. I will say I was at the dealership a while back and getting other work done and they kept telling me it would be expensive but they never gave me the estimate I wanted nor were they able to tell me anything about what more I would need for the job. So ive been looking online shopping around seeing what I might need and also wondering how much I can repurpose from my current setup. Help me out guys if you can thanks in advance
