So, bigger wheels would (obviously) help, but a new axle with "spacers" would also be a solution?
Torsion axles do wear out and the trailer "drops" with the loss of torsion. Adding spacers to a new axle or your existing axle if it's still good would raise the frame and body and eliminate the need for the casters you have. Your ground clearance (distance from pavement to axle tube) would be the same. You might be able to get torsion axles with longer arms too.

I just bought 2 flexiride axles that have adjustable angle of the torsion axle. I will post how they roll once I get them on. Especially excited to add them to the boler with the low clearance.

As far as we can tell, the trailer hasn't dropped at all. The wheel is still in perfect position in the wheel well.

To add spacers to the existing axle, I suppose we'd have to lift the trailer off of the frame? I think that's a doable thing, but I still have no idea where the screws are that hold the trailer to the frame (and I'd really like to inspect those).

LP, if your axle is bolted on it's easy. You don't unbolt the shell from the frame. Jack the whole trailer off the ground, unbolt the axle, add the spacer and bolt the axle back on. I used the 3" lift kit from Orbital Machine Works. Very nicely built too. Took me about 3 hours to do it by myself.
My axle was good, I just needed more ground clearance because of where I go.

So, the procedure would be to jack up the entire frame, support it front and back with crossbar/beam things, and support those with something solid (not jacks) and THEN undo the axle? That doesn't sound too bad.

COULD we inspect the screws holding the body on while we're at it?

And would this also be the procedure to inspect or service the brakes? Hubby has looked under there and says the wiring is a "rat's nest," so he will be addressing that very soon.

I'm planning to flip the axle on my 79/1600, it has the 4 inch drop axle.
Will I have to have the axle bent to put the hump up instead of down.
How did this work out for anyone that has done it. I intend to use the trailer off road a lot, so looking for maximum ground clearance under the tanks and axle.

I don't know of anyone that has done this, but it might put too much strain in the axle where the tube is welded to the spindle. I'm guessing Dexter would say no but that would be the safe answer. I saw a "stickey" that was really high off the ground when I was in Moab but unfortunately I could not get a close up look at it. Is your drop axle mounted above the springs. Were you planning on mounting it below the springs and flipping it also? You would raise your trailer 4 inches with a straight axle and if you mounted the straight axle under the springs you would lift the trailer 8 inches but still have the same ground clearance. With 225-75-15 tires you would pick up another inch. Lots of possibilities here.

I plan to mount the springs under, with new perches and turn the brakes over. I'm debating a new straight axle, if I can swap the bake drums etc. on to the new axle. I plan to put some 235 75 15 tires on it. I mounted these with the stock setup and they actually fit fine. I've taken the fender skirts off, so that won't be an issue. Thanks for the help.

I can't answer brake swap questions, but I also went with a Dexter straight axle on my Bigfoot. I'm in Moab now, and though I haven't taken it anywhere crazy yet, based on where I have been, I think it's got plenty of clearance for me. And I still have the 14" wheels. It's sprung under.

I'll let you know if I run into anything that I don't have enough clearance for.

I think for me, the clearance with a straight axle, sprung under, is perfect. I did drag the front and back end of mine through a deep dip on the way to my current campsite, but luckily it was all soft sand.

At first I thought "well maybe I could use another inch or two lift" but after thinking a little more on it, I think the limits of my trailer clearance are just right. I really have no business pulling a trailer down roads any crazier than the one I'm currently on.

Though when these tires wear out, I'll probably upgrade to 15" wheels and then I'll have a pretty easy choice of another inch lift with new tires.

Not sure what you mean by rough roads, but after spending some time in the desert with my Bigfoot, I'll say that even with good clearance, it's not the best desert rig. I mean I guess any trailer is not great, but the width of the Bigfoot could be a problem.

It wasn't a problem for me, this time, but my early (smaller) Tacoma fits perfect on the smaller desert and forest two-track roads, like any Nissan, Jeep, Chevy S10, Ford Ranger type truck would. The Bigfoot is wider than my truck, both the wheels and the body. So it's riding the very outside edges of the roads I'm driving down.

It didn't matter on this trip, but I could see it mattering in some other areas. I also see myself not using it if I want to get down crazier roads. I'm not too good for sleeping in the back of my truck, or a tent

Big foot axle flip

I used the stock axle with the springs over. The shackles look to be longer than what I would think the stock ones were.
I now have 235 75 15s on it with lots of clearance.
