Like the way it looks all blacked out now Mike!
Yes, I was following him up that FSR with him towing said trailer for our trip. The Timbren suspension looked to be doing its job very well. The trailer stayed glued to the road, no hop, no bounce no wandering, and it stayed planted to the road very well. My CDN M101 with the stock leafs and new OEM shocks was also doing very well, similar to the Timbren with a little more wallow as it is heavier and more top heavy. If you are looking at suspension options, the Timbren looks to be an EXCELLENT option. If I were building from scratch, I would likely go this way for a number of reasons, mostly for the superb ground clearance, simplicity and stout build quality.
BTW, this is one of the nicest pieces of ply/glass/epoxy I have seen, and I lived on and around boats for much of my life. Almost as nice as my trailers lid (which Mike also built)!!
PS are my mud flaps ready yet? lol
