Which replacement spring for a 2005 Bigfoot 21RB travel trailer
Published 08/29/2019 >
Question:
I got underneath the trailer, but did not jack it up and put it on jack stands so this is a all wheels down, laden weight measurement as close as I can estimate, since the spring eyes’ holes are filled. I measured 24.5” middle of spring eye to middle of spring eye. I also measured the diameter of the axle by measuring the distance across the U Bolts at 2.5”. Hope this helps. Thanks again.

I looked up your 2005 Bigfoot 21RB and found that it is a tandem axle trailer. I couldn't find the GVWR for your specific model though. Most seemed considerably lighter than what you mentioned so you might verify what you have. Or you can get me the diameter of your axles and that would be a good indicator.
The axle info should be listed on a sticker that's on the axle as well. Or it can be listed on the VIN plate/sticker of the trailer.
