Yes , you need a truck, a real truck. Not a SUV. The bigger the truck, the better. For most people, a 3/4 ton (2500) is enough. Personally, I’d want the diesel. You said money was not an issue. If you need/want more cargo capacity, get a 1 ton. Then, you can take almost anything with you and it’s not a whole lot of money difference between the 3/4 ton and the 1 ton any way.

Have you looked inside the EMS box under the dinette? Pull the top off and check the wiring inside for a short. It will be obvious if there is one.

If the hot and ground are shorted you'd be able to see that by testing for continuity at the pins on either end of the cord. It could actually happen if one were to crush (run over?) the cord on a hard surface like a concrete campsite pad.

Your incoming voltage is fine. Earlier you stated the the Klein showed, "they all were indicating hot/grd rev" Does the readout on your onboard show any errors? Look under your dinette seat at the back side of the power inlet (where your external power cord plugs in) and make sure all the wires are tight and not burned. Also examine the inside of the inlet (from the outside) to make sure there is no scorching which would indicate an overheating due to a poor connection. Unless there's direct short in the plug or inlet port, I done understand how the hot and ground could be reversed. Keep posting until we can work this out.

Personally, I would swap from the South Rim of the GC to the North Rim. There is a world of difference.

Just so I understand...You were plugged into a power post at a campground. Everything was working fine and all of a sudden everything just stopped working. When you used the Klein tester, were you at the campground, at home or both? At home your 30 amp power inlet on your house has always worked in the past?

Grab your springs, order some new shocks, put some ice on the lobsters, throw it all in the truck and head south. We'll get them on. We don't "suggest" you to buy anything like the HH folks do. I might as well make a cardboard sign that says "Will work for food!"

Problem was solved on 08-01-2024, but here we are, all still blindly answering.

To actually check the wiring, it's much easier to just pull the head unit out of the wall. Remove four screws behind a pop off trim ring and just pull it out. If it's like mine there's not enough wire to set the unit down on the bed so you'll need something on the bed to support it while you check the rear connections. While you're back there, make sure everything else is plugged in securely. Also make sure the previous owner was not using that area for an easily forgotten hidey hole.

I didn't, thus the next three trucks: 1500-->2500-->3500.

@Mike and Carol Your pics look remotely familiar. These were shot in 2008...

I'm not entirely sure what you are trying to do but see if this helps you.

L shaped.

Please explain your motivation for wanting to de-rate these springs.

I do realize that some folks would rather own a car than a truck. Your 2021 Toyota Land Cruiser per your information says its cargo capacity is (a dismal) 1360 pounds. From that number you will have to subtract your tongue weight (600 pounds) an Andersen Hitch (65 pounds) and two adults (~330 pounds). Now you used up about 1000 pounds of cargo capacity. That means no more than 360 pounds of additional cargo can ride inside the vehicle. You might be able to manage to limit everything else to that weight. Most could not, I know I couldn't. Just my tools alone weigh more than 360 pounds. Could I get by with less? Maybe, but not if I choose to stop to help when I find you stuck on the side of the road with a broken spring, and I always stop. Personally, I think you need a more capable tow vehicle. Edit: I just saw the pictures of your rear setup and I can say without any reservation whatsoever that you are overloaded. You are just one fender bender away from a serious lawsuit. I guarantee that if a slick lawyer gets involved he will take most everything you have because you are playing outside the rules set by the car manufacturer. Your insurance will likely deny any claims also. If you have any dreams for the future, give them up now, because they will want those too. This is exactly why you don't see more than nine people trying to tow a (potentially) 7000 pound trailer with what is essentially just a car. Many of us have gone to the heavy duty diesel trucks to ameliorate all the problems you could encounter if you're ever in an accident with a setup like yours.

All the U-Bolts supplied by Alcan have been 9/16". The OEM's (at least on mine) were 1/2". It is very important, if you buy the Alcans, to know before placing your order the diameter of the axles on your trailer. Most will be 3". Some of the earlier builds will have 2-1/2". One owner told me his (used) trailer had one of each. This, most likely, was from one having been replaced prior to his acquiring it. I'm not totally confident in the report that one owner said his axles were 2-3/8", but who knows? Measure them to know for sure. If you don't have a caliper or a micrometer or don't know what these are then you may have to result to the string method (but this does require some math.) You could use a C-Clamp as a poor man's micrometer. Just tighten it up on the axle just loose enough so it slides off, then measure between the jaw faces of the clamp.

Good point, about half of mine took a smidge of a turn the first time. Maybe two on torquing the second time. I've called it good as they have over 5000 miles on them now.

I don't, but a good many have failures on both sides at the same time. They may not both break at the same time as they tend to flatten prior to actually failing.

No, the only spring they make for these axles is the 2750 pound version. I changed out our original 5-leaf springs for the Alcans and I honestly can not tell any difference in the ride or the handling. Tali did most of the towing during our recent 5000 mile trip up to Maine and she said she could not tell any difference either.

That is the correct torque settings. All 1/2" bolts should be torqued to 65 pounds. All 9/16" bolts get 90 pounds.

I've been following the number of broken springs for over three years. All were four leaf springs and all have broken in exactly the same place and manner. Being a moderator here on the forum and an admin on the primary FB page, I've heard about or seen probably 30-40 reports of broken leafs. But because only about 10% of the owners are active on either or both platforms, I suspect the number of spring failures that have occurred is actually much greater than has been reported. There are well over 1600 Oliver TT that have be built. Elite I's comprise about 16.5% of them. Since they have always had the heavier 5-leaf spring pack and the 5200 pound axles they are the least likely to fail. I've not heard of any so far. That leaves nearly 1400 trailers that have the weaker springs all of which are subject to failure. As everyone knows, all the Elite II's built since 2022 have come with 5200 pound axles BUT they are still built with the 1750 pound 4-leaf spring packs. The springs are the weakest link in your suspension systems. I can not tell you that you WILL have a spring failure. There are many that have not. But I will promise you that, if you do, it will NEVER be in a convenient, dry, warm or cool, flat, smooth place. It will be on the side of the road or in a parking lot somewhere. Replacing one at home with all the tools you need is a challenge. Replacing one while you are on the road with no help will be daunting, dangerous and all but impossible. You WILL need more tools than you likely brought along. And all that's assuming you have all the proper parts with you in the first place. I've replaced a bunch of springs in the last few years and have some owners coming to Tupelo in the next few weeks so I can help them replace theirs. It is not an easy job but it is easier to be pro-active rather that re-active. If you are so inclined and can afford a set of the Alcan's, I highly recommend them. If not, buy a pair of cheap replacements to take along with you and some extra $$ to pay someone to install them for you. Don't forget to have a full set of new U-Bolts also as they are a one-time use only item.

At about $16 per U-Bolt, Lew would probably like to have those back.

The two rear jacks are exactly the same mechanically as the front one, they just don't have a control head. Barker makes them specially for Oliver so you won't find them listed online.
