Recently I purchased a 1986 16' Scamp
and upon inspection (of course) I found a few problems.
I the floor had rot in the front and rear and the frame had numerous poorly repaired cracks.
I was aware of the repairs, but not quite aware of how poorly they were repaired and the inherent weakness of the original design.
There were cracks where the holse were drilled to attache the floor to the frams and where the frame was bent to form the tongue.
As you can see I cut this off and built a new lengthened tougue.
My goal is to reduce the tougue load on my VW TDI wagon and improve stability (Which has not been a problem).
Part of the moficfcation is to move teh side bath to the front and towards this end I found a used bathroom pan for a Sprinter van.
Another weakness is the tie in to the under door tubes to the right side frame forward.
These tubes are not fully engaged to pass the loads for the entire tube to the frame rails since the top and bottom of the tubes ate not closed.
I added the braces ahown on both sides along with reinforcements and closed the tubes so that the tension on the bottom of the underfloor tubes would also carry the loads.
I have the left side floor out and I am planning on adding support from the frame to the fiberglass hull to transfer the loads for it to the frame along it's entire length instead of focusing it all at the front and rear.
I have also added a 1 1/2" X 3" 11 Gauge tube under the existing top tube on the left. This extends like the right side to reinforce the tongue towards the front.
A part of the reinforcement was removing the sheetmetal bulkhead across the front and replacein it with two 11 gauge tubes to help stiffen the right structure at the door. This beam was moved the the rear slightly to allow room for the floor pan addition. I also continued this beam over to pick up the bottom of the fiberglass shell at the bottom of the door replacing the rotten wood piece.
In my opinion almost any of the early 14 gauge frames would be prone to failures at these points and should be inspected carefully from time to time.
I am adding a little weight
, but it is at a low GC and will add to the life ot the rebuilt trailer.
Part of the problem with the new addition is the addition of the black water tank under the floor and I am planning on gaining clearance at the front and adding a Macerating pump and valves from the gray system for a single point pumped discharge system.
Any thoughts on what I have done so far?
I plan to use the sides of the original side bath too form the ends of the wall at the junction with the hull. My plans are to cut off the Rhinohide and rough up the fiberglass and attach with epoxy and a few pop rivets.
