With the new length of the trailer finalized (34' bed), we had to weld on new axle mounts based on the trailer length. The suggested formula from the mobile home haulers was 1/2 of the bed length (34'/2=17')and then add 1" per foot of bed past the centerline towards the rear (34" back from the centerline). This will give the trailer enough tongue weight but keep sit close to the center of gravity.

This was the beginning of the trailer. It was a 60 or 70' long frame for a mobile home that was taken off the frame and then cut into three sections. We bought the frame for scrap and paid $50.This was the beginning of the trailer. It was a 60 or 70′ long frame for a mobile home that was taken off the frame and then cut into three sections.

This is the rear section which has the three axles on it. Of the three axles only one was salvageable. The other two braking axles were rusted out from years in the dirt.This is the rear section which has the three axles on it. Of the three axles only one was salvageable.

We planned on jacking the tongue section (24') up high enough that we could slip the axle section (10') UNDER the tongue section and clamp it together to drive it my cousin Hughs house to rebuild.We planned on jacking the tongue section (24′) up high enough that we could slip the axle section (10′) UNDER the tongue section and clamp it together to drive it my cousin Hughs house to rebuild.

For a 3 axle setup, you use TWO taller "C" sections and TWO shorter "C sections. The free spinning axle goes in the middle and the electric brake axles go on either side. That way the third axle only is only working with a load.For a 3 axle setup, you use TWO taller "C" sections and TWO shorter "C sections.

Installing the trailer wheels. These mobile home tires are 14 ply tires and can take 3,000 lbs per tire. They typically only last about 10,000 miles, but they shouldn't blow out, they'll throw rubber and go flat. The are 'rimless' tires with bolts that hold the rim onto the axle.Installing the trailer wheels. These mobile home tires are 14 ply tires and can take 3,000 lbs per tire.

Almost done with the supports. These supports help keep the trailer from racking on the road. They made a HUGE difference in stability.Almost done with the supports. These supports help keep the trailer from racking on the road. They made a HUGE difference in stability.
