1970 C30 flat bed delivery stake side

[rushingg149]

See previous post “1970 C30 flat bed delivery” for pictures of the truck.

I would like to retain the 12' bed. Need suggestions on the maximum frame length with regards to pulling a travel trailer.

Frame extended 2' between cab and rear axle.
Axle to axle is 13', rear axle to ball hitch 6'2"

My concern is the rear axle acting as the fulcrum and possibly decreasing the front axle weight.
I have an extra chassis and I can utilize the frame to beef up mine. The bed was mounted on wood but I’m planning on utilizing steel along the frame between the can and rear axle to beef up the frame and to level out the bed. I’m also going to clean up the end of the frame and add extra bracing. I can cut off the bed length if need be but would rather not.

Does anyone have any engineering experience, concerns, or comments.

One thing that you can do to help is use a weight distributing hitch to more evenly distribute the load over all 4 tires.http://www.summitracing.com/parts/CHT-17002/
