I have 3 trailers with the Dexter style rubber mounted torsion bar axles..... I like these axles for several reasons... . they tow better... . turn better, back better, and don't wear out like the spring style axle does... in that we don't have to replace shackles bushings and pins... .
I've put 2 or 3 sets of bushings and pins in my 5er travel trailer... . and it doesn't have near the mileage of the work trailers..... and my travel trailer really crabs when you back it up in a tight turn... . If my next travel trailer doesn't have these axles we are going to put them on.....
Hope this helps... .
