Trading to downsize

[speedster100]

We ended up buying a larger park model unit in our RV park this past winter and won't be staying in the 2015 3790RD as we have these past winters. We really do like the space & storage however it is alot of trailer when trying to find a spot to park in the Bluegrass Festivals we usually attend in the summer months on weekends. To get out of the house during the current Covid19 crap & with some warm weather we took a drive to our dealers lot and they had a 2019 20th Anniversary 3120RL on the lot. Looks like we've made a deal to trade our 3790RD on it.
Can anyone tell me if they've fixed the stupid undersized 50amp breaker issue on the hydraulic pump & whether they quit using the Thetford Aqau-magic toilets ??? We installed a Dometic 320 in ours and it is light years better than what came with the 2015 3790Rd.

Not looking forward to all the repairs that are coming, seems like I just finally got the 3790RD to where nothing falls off, breaks or leaks but as things have changed it seemed that downsizing 7ft or so made sense at this time... Besides we got a very good deal on the 3120RL...

Thanks in advance for the answers to the breaker/toilet questions...

Based on the number of threads on both subjects - it appears that Keystone has not changed OEM hydraulic system breaker to 80 amp, and still installs Thetford toilets.

The breaker swap from 50 amp to 80 amp is an easy $30/30 minute fix. Installing a dometic 320 or 310 is not hard but it took me loonger than it should have because I had to make a couple of runs to Home Depot before I got all the right fittings for my situation.

I believe Montana now installs the Dometic 310 toilet in the current models. I would swap it with your current 320. The same 50 amp breaker was installed last I looked.

Our 2020 MHC came with the Dometic 310.

Most of the newer Montana,s Come with the Dometic 310 toilet. As far as I know the come with the 50amp barker. With any new Rig you will probably be to doing some repairs.

Ours is a 2019 3791RD. It has the 50 amp breaker and the Thetford porcelain toilet. Been trying to talk the DW into changing to the Dometic but she hates to get rid of something that is still working. I'd rather not deal with the leak.

Thanks everyone, we made the deal to include the shop swapping out our Dometic 320 to the new trailer at PDI time. It's a 10 minute job as that is about how long it took me to swap out the Thetford for the Dometic 320 when I did it. Two days of removing stuff from the 3790RD (OMG how did all that stuff get in there !). Got it all emptied out in storage spaces and checked what I did when I swapped out the breaker shortly after purchase, discovered I left the old one mounted right there so I just swapped over the wiring back onto the original. Another 15 minute job when I get home after we pick up the 3120RL. The big job will be what to put into the 3120RL and what to put in the garage sale...........LOL.

order the 320, break foot pedal on Thetford. everyone is happy. keep me anonymous.

Is it the foot pedal that breaks on these? Mine seems to work just fine.
Also I see in online reviews that often the 310 is rated higher than the 320. What is the difference?
