Cool! I was wondering - is there a brace across your frame where they mount? Seems like they will try to twist the frame a bit. The ride-height difference isn't something I'd considered.
You have a lot of off-road experience with your trailer, whereas I have only a few miles of rutted dirt roads with mine. But, I feel that you're not giving enough credit to leaf spring axles, which came first, and still remain. Look at 4wd vehicles & off-road-specific trailers: all types of springs are used (leaf, coil, and airbag/hollow rubber -Aeon, Sumo, Timbren-). But, if leaf springs were so insufficient to do the job, why were all Jeeps (the first brand most people think about when 4wd comes to mind) leaf-sprung until '97 (56 years)? True, leaf springs are old-school, can be rough, and jarring. But, if one breaks out in the wild, you can use a ratchet strap to secure it, and get to civilization to find a replacement (if using common sizes, no problem, they're everywhere), or if using re-purposed automobile springs, junkyards. Coil springs have no temporary fix, nor broken airbags, that I'm aware of. And the hollow rubber springs: unless you carry a spare rubber "donut, puck" with you, replacements are rare in the wild. I have had a leaf spring break once or twice, and limped home with it that way. There were two places within 5 miles of my house with matching replacements in stock! Another thing I feel favoring a leaf-spring axle is the usually strong spindle-to-axle weld: I know of no one that had their spindle break off, while I know of occasion where a spindle broke off a torsion axle (same sort of working motion on a Timbren; I was wary of that when I was deciding an axle upgrade. I upgraded a weak leaf spring axle setup awhile back, and chose a Dexter 3500 lb axle with brakes, for $400 ( after adding installation hardware, shackles, springs, etc)... The other system I considered was a Timbren with brakes, for $800+ (I don't know what it would've cost to install it). With either choice, I would've had to (and did) beef up my frame with heavy steel reinforcement, for $75 more. I chose the Dexter because of familiarity, trust, experience, and cost. I, perhaps, put too stiff of springs on it (3000 lb set) since my trailer is about 1750 lbs, loaded, but I can easily step that down to less, since new 25.25" springs are under $30 each.If you order the wrong rating with Timbren, it's $100-200 to change the spring rating (torsion axle- you can't change the rating, coil springs- replaceable like leafs= cost unknown). It's a choice worth considering well; buy/install what you're comfortable with (figuratively, physically, mentally, financially).Dave Nathanson wrote:... I'm not really interested in the lack of an axle because after 13 years of wheeling with a straight axle, I have never had a problem with the trailer axle hitting anything or hanging up on a rock. Just doesn't happen. But I am very interested in a softer ride that won't break leaf springs and knock teeth loose. I fully expect my whole trailer will last longer with this Timbren suspension instead of the overly-stiff utility trailer leaf springs. I believe I have figured out why I was breaking leaf springs (has to do with the wrong way the shocks were mounted) but I am still really excited about this Timbren suspension....

Put a wheel on it!
This is me taking Mengle pass. The trailer has a straight axle. By putting the wheels on the rocks, you go
over them. (instead of getting stuck behind them). And of course the axle rises out and out of the way
as the tires go over the rocks. Is your off road trailer too low?
