RE: Low power?
For a nominal voltage of 120V, ANSI allows a range of 104.4 - 127.2 as acceptable. However, NEMA requires electrical equipment be able to operate within a range of 103.5 -126.5. Following either requirement, the OP is able to use his AC within a safe, specified range.
As an aside, the (one way) resistance of 50ft of #8AWG wire is 0.031 OHMS. The round trip resistance total would be .062 OHMS. Assuming a single A/C running at 14Amps, voltage drop is (E=IxR)=14x.062= 0.868V If both A/C units are turned on, total amps would be 28, or 28x.062=1.736V drop. With 111V in at the house, minus 1.736V drop, the voltage at the RV should be about 109V. OP claims 108V or about right.
Still within "code" range of 104.4V or 103.5V for acceptable operation.

RE: Travel Trailers vs Motor Home
“And with a travel trailer and no "tow vehicle", you are "trapped" also.”
Who would have a TT and not have a tow vehicle, Larry?
How about this guy:
"The guy next to us had been there for 5 weeks in his travel trailer. He was supposed to be there for 3 or 4 days, but blew the engine in his truck and was stuck"

RE: Travel Trailers vs Motor Home
I have observed many many times in RV parks and campgrounds people stuck for days at a time with complicated mechanical issues with their newer Class A MHs and repeated visits from mobile repair technicians. In 16 years of towing a TT I never had a serious maintenance issue with my R-Vision 28 foot lte Trail Cruiser. Worry and maintenance free for fun and fishing in local areas whereas Class A folks set in chairs at campsite with all MH outside compartments open trying to solve their problems. Cheers to the truth and the d
Now that there is one of the funniest posts I have read on RV.NET in 17 years as a member here. Great sense of humor Nam!

RE: Travel Trailers vs Motor Home
With a motorhome and no towed, you are “trapped” in the campsite IMO. No one wants to break camp to go to town for lunch.
And with a travel trailer and no "tow vehicle", you are "trapped" also. Not sure what you point was, except that with a motorhome you can travel without a towed.

RE: Tuning a 03 Cummins ISL
Check/change your air cleaner. It might be clogged and restricting the amount of air the engine is able to pull in.

2017 coachmen Leprochaun slide mechanism
Anyone know who makes the slide mechanism? The slide is driven by a gearbox at the top and bottom and has a rotating shaft between them. The bottom is not synchronized between top and bottom and we need to know how to do it. The top pulls in before the bottom gets in.
Brand name, instructions, etc. Even a “YouTube” video.

RE: Where to get Replacement Wheel Bearings -Old Camper
Look real close at edge of bearing. Most times there is a name and number. If can't find that, take the races to a trailer parts/repair shop. Note; if you don't tell the bearing it is going on a RV, it will never know. Much more likely to get what you need from a shop that does not fix toilets and stoves. You are looking for trailer parts, not RV parts.
Good advice. I googled "wheel bearings", and it gave me Autozone, Advance Auto, NAPA, etc. Get the part number off of the side of the bearing, and take that to any of the above.

Coachmen Leprechaun slide motor came out
2019 C and the gear drive that deploys the driver side slide has managed to get outside the body. This is the bottom gearbox. There is a shaft coming down from the top gearbox and it is still inside the body but gradually comes outside toward the bottom gearbox. The rubber gasket is torn all the way down from the shaft coming through.
Strange thing is that there is no apparent damage to the wall at the bottom where the gearbox is outside. There doesn’t appear to be any easy way to get it back inside.
If I didn’t know better, I would say it came that way from the factory.
Anyone ever see anything like that?

RE: Considering first DP - any advice?
I have had DPs since 1997 even a Monaco Dynasty with 4 slides and 450hp.
I hated that thing and only kept it a year.
Interesting, I always considered the Dynasty to be the gold standard of
RVs. Never heard bad things about them before.
What made you hate yours?
Payments???

RE: Considering first DP - any advice?
Here's something that's mandatory for me. When you bring out the frontroom slide, do the storage compartments come out with it? Mine do. If they don't, it's a real PITA to get into the storage compartments that are back under the slide outs.
Bill
That's funny, the bins coming out would be a deal breaker for me. If those bins come out you don't have a pass-thru basement. If it doesn't have a full, flat floor, pass-thru basement I'll keep looking.
But that's just me and I'm glad we all have a choice.

Pass through is better!

RE: More generator vs. AUX-START
You have two sets of batteries in your coach, chassis, and coach. When you push the Aux/start button, it ties the two sets together such that you are now using BOTH sets together to do what you want to do (i.e. starting the coach, or starting the genset.) The chassis battery starts the RV engine. The coach battery starts the genset. When you push the Aux/start button you add the chassis battery to the coach battery (in parallel). It is pretty obvious that coach battery is somehow not connected properly to the genset. Find that problem.

RE: Power cord connections melting
It is true that because RV's are plug in devices that the above figures which are from the electrical code are not enforced.
Doug asked you for "a reference". "from the electrical code", it is a vague comment that purports to be a reference. Here in USA we use the NEC to spec wire sizes, etc. In Canada, you use CEC to do the same. No where in the NEC does it say anything like what you stated about requiring reduction of amps to preserve a plug, etc. I would like to see the section of the CEC where they do. Please post that specific section of CEC so we can all gain knowledge.

RE: Exhaust brake not working
And, very easy to verify if any type of engine brake is working: Use transmission down arrow to select a gear where you are close to the upper end of the RPM range. Turn engine brake on/off/on. Since the transmission is now a constant, easy to see if you have added braking HP.
Brett, thanks for that suggestion. Never thought of that.

RE: Exhaust brake not working
Curious to know how you determined that exhaust brake isn't working? If the brake in your coach is activated with the dash switch, it will close automatically when you begin to slow down. Typically, this will also cause your transmission to downshift to a lower gear, (typically to 3rd) The actuator for the brake is an electrically operated solenoid that pulls the brake valve closed. I believe you also have a Cummins ISC engine.
The problem with determining it is not working, is that it only activates when you are slowing down, and then you have to visually see the solenoid action. That is not an easy task. To see mine work, I have to raise the mattress, and open a hatch while the coach is driving. This requires a second person to watch while I drive.
You can test the operation of the valve by applying 12VDC to the solenoid wires, while not moving, but that doesn't guarantee that the 12VDC will be applied when driving.
You also have to periodically lubricate the valve mechanism which special exhaust brake lubricant. This will insure that valve mechanism is free to move. They are known to get stuck from rust. You can test the mechanical operation with your hand by turning the operating mechanism to verify it opens and springs closed when you let go.

RE: Inverter wire size?
I=P/V
I=AMPS
p=POWER (OR WATTS)
V=VOLTS
I=425/12=35.4 AMPS
10G wire is rated 30amps.
I would go with #8
