Question WJ rear coil springs - How strong and resistible they are to heavy load?

Hi everyone!
I need your thoughts on this.
I'm planning to buy some new home appliances and most likely will transport them one by one in my cargo compartment. Some appliances are relatively heavy (refrigerator, oven, and so on..). Is there any way that I can privent rear-end sagging that I assumed can occur afterwards? Or Jeep's rear coil springs are strong enough to resist heavy load up to allowable/recommended by manufacturer maximum load weight? Any ideas? Any experience with?

Thank you!

I really don't think that a refrigerator will fit yet, I wouldn't put something that heavy back there.

You have nothing to worry about. I towed a a 5000 pound trailer from Alaska to the midwest, the jeep barely sagged with the weight

Why not? Are there any specific reasons?
The refrigerator has about ~360 - 400 lbs. net weight. Is that too much for cargo compartment load?
Just curious ...

If you can get it to fit, in the back. Your payload max is 1000 lbs(cargo and pass)

I've had a dishwasher and washing machine at two different occasions. If the refrig. will fit, the jeep can handle it. The only thing to watch is if you are at max capacity, take it easy on corners, accelerations, and decelerations and your jeep will be okay. Definitly no off roading with the refrig. in the back and you will be fine.

I was thinking of like a 21 cubic ft frig. If you can fit it back there, go for it.

Of course, I had a huge generator, two coolers, and towed a 15 ft camper to gse. Yeah, the springs will take it.

Yes, I know that and this part is a bit confusing. The certification label attached to the driver's side door pillar says that GVWR (Gross Vehicle Weight Rating) is about 5,450lbs and Rear GAWR (Gross Axle Weight Rating) is 2,950lbs, and the manual says "load weight should not exceed the GVWR and F/R GAWR.
If load weight should not exceed the GVWR does that mean that I can load vehicle more than recommended "max. Payload"?
So, what's the correlation between "payload" and “GVWR”?
