That looks a lot better - yeah mines a "low rider" too - Scamp must have a different frame than the Pacer....

Ken J.

They are all different, but similar. Here's a cross section of mine. The grey is the original frame, the orange is what was added to convert to a trailing arm using 0 degree. If you want I can send you a full sized diagram so you can go out and measure for yourself and compare.

There is a full description of a scamp axle swap either here or on Yahoo scampers with pictures showing the frame. I've got a years worth of fixes to catch up on documenting and finish posting before I will get to how I installed mine last week.

Here's a link to the post here:

Till I can post the entire fix, I will post two more pictures. One of the trailer post axle swap and the other of the streetside view of the metal addition. The rear is to your right in both.

You'll find before and interim pictures in a lot of my posts here on FGRV in other threads.

I've tried to enhance the drawing a bit, hope this shows everything a little better.

BTW, Final hitch height is pretty close to 18" - I'll know the exact once we get it loaded for travel.

Mine was a leading arm and I changed it over to a trailing arm . I used a Dexter #9 axle 22 1/2 down. My floor raises up by the dinette.

I bought mine from red trailer. Site http://www.redtrailers.com/ On my Scamp I had to add some rectangular steel

Great pic! What I have now is just a 2" or so flat bar under that side of the trailer - I guess I could replace that with the bar that you show - hmmm major surgery....

With the trailer up higher like that, do you get any sway while towing?

thats real interesting kevin. i just replaced the axle with an original from scamp. looking now i kinda like the trailing arms better. not sure. did you run a cross beam linking your rail additions for rigidity? the box on the original frame seemed thin and i worried it might shift under the loads. was the replacement tube thicker? i posted some pics in mods section under "scamp gets an axle". it went right in and measured perfectly to track straight. did you have any trouble locating it front to rear or side to side? also did it change the weight proportioning front to rear and get any sway side to side at rear? im not sure if the dynamics of the axle pivot point change loading or is it the location of wheel center(bearing) that determines balance? i think it should be wheel center but your towing experiences before and after would really tell. thanks
