Sask, that would explain the difficulty in finding the Monroe parts. I have not seen another manufacturer of similar components. I wonder if there is one with shocks and brackets for an RV retrofit?
Coot, thx for the great pics. I have never seen torsion suspension before and it took me a bit to see that there is an extra steel member under your I-beam to supports the axles. Obviously lots of thought went into what you did. I am thinking perhaps I could bolt an 1/8" plate onto the I-beam that is say 12" long x 6" high (approx.) with an appropriate bracket with gusset welded to the plate before it's bolted on. Then there would be no welding to the I-beam.
I have to wonder if Lippert or anyone else has a specification for allowable hole sizes, location and spacing in the I-beam? The frame near/around the axles is an obvious high stress point and I am worried about potentially weakening anything by drilling. The internet is full of stories and tragedies about cracked Lippert frames...
I noticed the Sensatrac shocks. Anything particular about these like diameter or dampening strength? If I can still easily get the Monroe trailer retrofit shocks, think I'll just go with those. But then if at any point in the future they had to be replaced, could they be matched up?
