I want to remove the existing truck bed and have a nice steel frame flatbed with solid oak flooring and stake sides created for my ranger but wondering about some of these issues below. I will be hauling mostly residential furniture and appliances, etc. (no heavy equipment). Any constructive input would help! - Since not 4wd and only 6 cy - wonder if hauling stuff will wear out transmission quick? Can I upgrade trans? - Should I replace suspension with more heavy duty parts? Will it do any good given the fact the frame itself if the most limiting factor? - Can I replace camshaft with better one? What can I say - the truck is paid for and can't really afford a box/moving truck right now - but need more hauling capacity.
