I replaced the axle on my '99 Scamp
13 earlier this year. I bought the axle from Scamp so that I was sure to get the correct one, plus, they had it in stock and shipped it out within 2 days, I had it within 4 or 5 days. The wait to buy it direct from the axle manufacturer was about 6 weeks.
I had a local metal fabricating company install the axle. I gave them Scamp's customer service number to call if they had any questions. They did, indeed, call Scamp and received all the measurements and suggestions from the Scamp folks to install the axle as a bolt on, instead of welded on. Will make any future servicing much easier. They said the folks at Scamp were extremely helpful. Not certain they would be so helpful if you bypass them for purchasing the axle - just a thought.
Plus, now is the time to add brakes
, if you want them and don't have them. Some states require them on ALL travel trailers that use their highways.
Here is the label from the new axle, as you can see, it is a 2200 lb axle.
