Base plate ?

I built, and installed the base plates for both my 2005 and 2012 Libertys. I saved a ton of money, but being a welder/metal fab by trade made the job easier. The most difficult thing for me was to R & R the front bumper grill assemblies.
For the average person, don't attempt it yourself IMO.
And forget getting any base plates to interchange....except for the same make and model.

Not likely. Baseplate from a Wrangler might not even fit a different model or model year Wrangler.

How difficult to mount depends on where it attaches, whether or not chassis modifications are needed, and how much bodywork needs to be removed and replaced. I thought, from the instructions, putting a baseplate on my Honda Fit would be easy. I was considering all those years in my teens when I was doing body work in my dad's collision shop, i.e. coming to the job with some experience taking cars apart and putting them back together. It was not as easy as it looked.

I had planned to have a RV shop do it, but they couldn't get me in for a couple more weeks, and I was in a hurry. The job took me four hours, spread out over two days, in the sun on a concrete driveway. There was at least another six hours of cooling off and rehydrating.

Tearing apart the front end, and removing the inner bumper to get at the subframe horns, was easy, about an hour. Drilling two holes, laying under a low car, was hard. I had no idea how tough that subframe steel was, but it quickly dulled a titanium bit. I now know to figure at least one or two drill bits per hole. I had to remove some extra pieces (headlight, washer bottle) to get the drill into position. Bolting on the baseplate was easy. Reinstalling the inner bumper was hard, turned out that it is bowed, straightens out when removed, had to be leveraged back into position.

The job would have been easier with the car on a lift. The job would have been easier in a cooler space, or at least in the shade. It would have gone faster with a better drill and a good supply of bits. There were a couple of places where it would have been easier with a second pair of hands. The dealer, in making an installation estimate, considers these advantages you don't have DIY in the driveway.

Find out what baseplate model fits the vehicle you plan to tow, then download the installation instructions to decide whether this is work you want to do. I've you've not yet chosen a towbar, get instructions for a couple different brands, because sometimes Roadmaster, BlueOx and Demco do things in different ways, Roadmaster particularly because they don't always do a baseplate, it is often a pair of mounting brackets for a baseplate piece that comes with the tow bar. Roadmaster would have been a lot easier for me because it didn't bolt to the sides of the subframe horns, instead the baseplate replaced the Fit's inner bumper using the OEM mounting bolts. Some of the simplest installations I've seen consisted of bolting to the mounting points for factory tow hooks.

Can a baseplate from a Wrangler fit a Liberty ? Is it difficult to mount a baseplate?

My local Hitch place says $400 labor.

I can't help about the fit...but, I just installed a base plate on a 2017 Ford explorer this summer. Pay the $400...believe me...that is well worth it :)

Base plates are generally pretty vehicle specific.

I just had a Blue Ox base plate mounted on our '02 Liberty. It requires removal of the grill and the rubber bumper cover. Might have been able to do it myself but just so much easier when vehicle is on a lift and eye-level instead of me crawling around on my back.

My local mechanic charged me 2-hours labor ($100) to do the install. Money well spent and looks like a million bucks. Best part is that I still have skin on my knuckles. :)

Can't speak to the Jeep question.

I installed the Roadmaster base plate myself on my Honda Pilot. Roadmaster estimates 3 hours labor, so $400 is not totally out of line. It basically took me all day, as the whole nose assembly had to come off, and I basically just took a lot of time to ponder each step. Also, there were few screws that needed to be removed that Roadmaster didn't mention in their otherwise very complete instructions.

Ooops. Bad info from me!! I deleted.

In my quick run through of Blue Ox baseplates from 2002 to 2013 for Wrangler & Liberty models I found none that share the same baseplate numbers.

$400 dollars is probably a fair price to charge for the installation.

yep if I had installed mine myself I would have spent that $400 for band aids.

Without exact Year and Model of the Wrangler and the Liberty, can't say for SURE. But based on how specific Base Plates seem to be, and again without the details, I'd rate the odds as 99% NO.
Send the details on the vehicles, along with the Tow Bar you have or are considering, and we can take a look.
All the manufacturers provide detailed base plate installation instructions, and that includes a picture of how it looks installed. That can help you decide which one you want. Instructions also include labor estimates.
