See-depends on user. The added braking of the acme screw would be enough for me to switch. The added capacity, length&weight, of the 4500 Id be tempted to replace both fronts.
Our Atwoods the fronts like to coast a bit after releasing button when lowering camper, to the point I often 'bump' the up to stop.

Replaced all four 4600's on my previous 10 yr old EC 850 with the then new 4800's. Son-in-law has it now and is doing well, but it has only been a year or so.

Replaced the front jacks with 4800’s two years ago. The camper is more stable when raising / lowering. The 4160’s would bind terribly. Very happy with upgrade so far.

I had 4600 jacks on a camper built in 2004. This Summer several of the jacks started out really stiff and making noise. Three seemed to recover but one failed entirely. I called Tweetys and they sent me a 4800 jack. I was very happy with the service. Jack was shipped that day from Georgia and arrived at my house on Long Island in under 48 hours. The 4800 jack is a few inches longer. I understand that is necessary because some truck beds are more elevated than in years past.

The Tweetys rep told me I should have run the jacks up and down about twice a year. I don't think I used them more than 4 or 5 times in the 8 years I owned the camper. I certainly never tried to take them apart and do any maintenance.

Interesting, this popped back up after 3 years. I had quit thinking about replacing the jacks. I just didn't want to waste money replacing the 4500s with another jack that probably wasn't any better, and I know the 4500s aren't strong enough for my camper.

I still haven't replaced my HJs. Didn't get a wide spread warm feeling that the 4800s were any better than the 4500s despite the corporate bragging. A second jack failed in 2016, only working when unloaded, so I've been using a hand drill and the hand crank for 2 years.

Everything I read about ACME thread jacks said they were cheaper to make, but the 4800s cost more than the ball screws and both are quite a bit more than the Riecos.(jacks only) But then I'd have to buy motors if I went with the Riecos and the weight capacity is less. It's a big investment.

It isn't that much trouble to hand crank, but it would be nice to just push a button.

If I find some on a real sale someday, which I have never seen any discounted more than $10 or $15, I may buy them.

I’ve got an almost unused 2017 camper with an already broken 4160 on the rear.
It seems they quit making them already, which is annoying.
The camper has 4800s on the front. Maybe I’ll just put some of those on the rear.

Are the Reico jacks any better? I could see if I can sell these things to offset the cost of converting.

So, the camper came with the heavy duty 4800 series on the front but the light duty 4160s in the back. It’s one of those light duty ones that broke.
For now I’m just gonna upgrade the rears to the heavy duty model too, and see how that goes.

So here’s an unexpected development: the freakin’ HJ 4800 is about 3” longer than the 4160.
Hangs down a bit further than I’d like.
I can make some adapter plates to raise it some, but I’ll have to drill some holes in the nice powder coated brackets on the camper.

I just got mine today and discovered that the mounting points, put the jack way too low compared to the 4100 that were on my camper.

I have to figure out how to make them work now.
