easier to stick with what you have now. You may be able to just replace part of a valve.
Just a friendly suggestion: before you load up the entire family for another long distance adventure with an unknown 30 plus year old MH, do some small trips to get the bugs out. Apparently, the previous owner did not disclose the issues you are finding and there will be more. Better safe than sorry

Alright. Got them out. The flange part appears glued to the tank though so it may be easier to just rebuild those valves if I can get the parts.
I’ll look at them today and see.
Also got the toilet out as the vacuum breaker is leaking when flushing.
Can somebody confirm the original toilet is an Aqua Magic GL and are there still parts for those? Thetford website doesn’t even list them. They have a couple newer models that appear identical in the parts diagrams but they don’t have the same part numbers.
Thanks!!

Thanks Peter, fully agree with the smaller trips. We had done a few drives without full camping in the days before but there was nothing available close to our city for a full camping with hookups so we took the chance.
I think those plumbing issues may have been winterization related as he had confirmed all worked before (unless he lied, you never know)

David, throw the old toilet away, you will find it to be real gross once turn it upside down. New plastic toilets are cheap, porcelain ones closer to $300.00
You may have to mess with the mounting or turn it a slightly different direction.
Yes, its fun to spend your money

Thanks Peter!
Indeed the bottom didn’t look too good. While there was no mould or grim there was lots of rusted bits and although it was mostly working it looked like it would be a ticking bomb as to when the next failure would happen.
I ordered a Thetford Bravura, a direct replacement with the same mounting holes according to Thetford’s website.

About 13 years ago, tried repairs on the old dump valves on the 310. Still leaking! Gave it up and went with the valterra system. No leaks to this day, and no adapter needed for your common stinky slinky! That is why when the old valves were not working on the Zephyr (350LE), I opted to install them. They also have a cable system for the remote handle. Not a bad install, just ABS is not so ready available!

Thanks. I did already order the repair kits so I will see. Seeing how hard they were to get if it leaks again I’m going to Valterra valves and redo the piping.

looks exactly like mine when I bought it new in 1985 .many many miles later we just got back from a cross country trip on the new motor and engine .mine made about 230,000 miles . lots of things will end up on your list but never travel without your tools and the RV towing insurance .we have used it 3 times in the 34 years and otherwise would have spent alot to tow/haul as you are learning .good luck congratulations keep us posted.my rig went all over CAnada to viit realtives .my wife is Nova Scotia , siblings in Vancouver,Ottawa,Newfoundland ,Parry Sound and more

there is never anything wrong with the generator, until the day you really need it. If you live in the south, you know what that means.

Nice Paul! I always have a bag of tools and a good multimeter
Nice to hear the drivetrain can last this long. I look forward to more adventures but those will likely be next season as I’ll be fixing the few bugs I have discovered this fall, reseal everything up top and then I suppose it will start getting cold...

good luck wave at the relatives in stillwater and check out their great astrophotographer (wifes cousin ) lots of good folks on here to get you through the rough spots .I cant believe how good the new generator is compared tp a 34 year old kohler was yours replaced yet > new tech is so much better

Nope. Still the old one. It appeared to run good though for now

Fuel gauge question: when you turn off the ignition does the fuel gauge stay where it is or does it drop down to zero? Mine stays right there.... always 3/4 full so I’m wondering if it is power to the gauge, sending unit, or gauge itself. I will pull the facia and check for signal but I thought it was weird that it stays there with ignition off.
Thanks!

Good . That tells me this is a gauge issue and maybe not a sender issue so I can drive around with ohmmeter and know the level until the gauge works
Thanks!!

Well... I pulled the gauge and it’s quite weird. Maybe I don’t understand how those gauges work but with ignition off I get about 6 k-ohm on the inhaler wire and with ignition in on I get 12V and zero ohm to ground...
I’ll look for a gauge diagnostic guide or study the wiring diagram tomorrow to understand how it all works.

your problem most likely is the sending unit or wire, I have 2 extra gauges to make my point. Brad was so kind to help me diagnose my problem (which was a sticky float that moved after I drove around a few corners)
to check the sending unit with your meter on OHM (I used 2K), connect 1 lead to sending unit wire and the other to ground. The result should be somewhere between 0-90 ohms.
The other thing he had me check was the ground connection to the gauge and a good ground to the tank
the third was, if removing the sending wire from the gauge, does it change the reading.
May be Brad can chime in and verify my test suggestions.

1988 345... The adventure begins!
Well the gauge is bad for sure as the needle fell off... but oddly enough the signal wire has around 6000 ohm with ignition off and it has full 12v with ignition on... I’m pretty sure the signal wire should be varying resistance to ground only and never live so it looks like it is shorted with a live wire somewhere...
