I second Glenn's advice. Whatever you do, unless you're very wealthy, don't take the trailer to an RV shop unless absolutely necessary. Anything like wheels, tires
, suspension and bearings are things any mechanic can work on.
I had a new axle
put on my trailer, and I had a local trailer
shop do it. Was quite likely half the price of having one of the RV shops do the same work.
Congratulations! Other than having no bathroom, that is exactly the Scamp I was looking at before deciding a Bigfoot
better met my needs. I live in my trailer for stretches of time so lots of space and a bathroom were a requirement for me.
