My first winter project has been to extend my frame and ad a trunk for chairs ect.

Nice Clean Job.......... Looks like it came with the trailer....... Did you have to beef up the bumper to the frame?____
a nice pic of that underneath would be nice if possible..
Have a Great Holiday

My frame extension

Gorgeous work Lyndon.
What do you think the weight limit would be that you could carry back there?
Did you add anything addl to the tongue to balance?

So what did you use for the box? Is it fiberglass?

Extended the Frame.............. Nice idea. I didn't even think of that route. that will beef it up real nice for you and the fifth wheel (gooseneck) setup you have is a plus and makes for a nice lookin rig. Got to hand it to you! Nice setup

The top and door are Fiberglass and the bottom and sides are 1/8 thick foam PVC with a skin of 24 gauge alum fastened to a frame made of 1/4 x 3 inch alum the whole unit weighs around 20 pounds I sure hope I don't get kicked off this board for not using all fiberglass. I will post pictures of project they are on another computer now.

The weight on my 5er toung is around 500 pounds, so no problem there this in for chairs and the like. i have also added adjustable spring shocks to bring my tired old axel back to its new height so I think extra weight will not be a problem.

I will now atempt to add pictures of the framework and skin

I don't think you have to worry.

The finish looks to blend in very well with the rest of the trailer.

Did you see the box I made? It didn't even look Fiberglass.

You did a beatiful job. Thanks for sharing.

So if I’m seeing that correctly, it looks like the Aluminum is the base tray. What is the sides made of that the lights are in and the spare tire are attached to?

Mike The bottom is alum with a carpet material on top of it to soften bouncing stuf while on the road. It has an alum frame as per photo 2 and 2 layers of skin [1] 1/8 foam PVC sheeting and a second layer of 24 gauge 6061 alum [a very rigid type] put on 1/2 of the trunk at a time starting at the body of the scamp and rolling it around as in pic 3 pop riviting as I went. The top is fabricated from fiberglass with a fiberglass door .

Lyndon, thanks for sharing the details of your mod. I do have a couple of questions...

The frame extension method raises (or lowers... which side is forward in the drawing?) the extended portion by over an inch: is the extension entirely beyond where anything was sitting on the frame?

The use of 1" tubing to splice the frame suggests that the stock frame is only 1" wide inside... is that correct and can you tell us the outside width and height of the frame material?

[1] It lowers the bumper about 1 inch and the reason I did this way was so I could weld inside and get a much stronger extension rather than butt welds. I still want to be able to jack the trailer using the bumper.
Sorry on these sizes as I was gussing not crawling under. The trailer frame members are made from 1.5 x3 inch 1/8 inch wall square mechanicl tubing so the inside is 1.25 x2.750 and I used 1.5 x1.5 x1/8 wall tubing for the splints. I must change my sketch.

Keep in mind that this is a 5W tow arrangement, which is far less susceptible to trailer sway, so rear loading is not as critical as it would be on a conventional trailer hitch. Because the hitch ball is mounted within inches of the TV axle, the overhang is inches and the trailer has very little leverage on the TV.

Did you add any drain holes (for wet chairs, fold-up tables, etc.) or don't you think that will ever be necessary? Perhaps you can reach down easily enough to wipe out any wet areas should they occur. Looks great! I wish we had a nice place to work on our trailer and old VWs during the winter.

Completely sealed . water tight, I did run a drain down from a water catching tray around the lid. it was quite a chalange getting the scamp through the 8 foot door , but with grandson s help we managed.

Have a great New Year! Cindy and I hope to see you at upcoming trailer events in 2008!

What mod did you make to your TV to get the hitch ball within inches of the axle?

This Scamp is a 19' model, which Scamp sometimes calls a "fifth wheel"... that's what Pete meant by "a 5W tow arrangement". It's not actually a fifth-wheel, since it uses a ball and socket coupling, but the hitch is located in the truck bed like a common fifth-wheel, typically "within inches of the axle".

Ahhh Haa!
