So the season has started!
We took it out first time for a quick night camping with kids and we are ready for the coming weekend. A few things that will need addressing soon though:
-slight drip off the black water tank. It appears to be at the joint between the valve and the tank collar. I have tightened that clamp quite a bit but I fear going further as it could crack that fibreglass piece.
-still no fuel gauge. I got a replacement one last year but I need to fix the wiring
-fuel leak at the fill up vent. Only a drop after filling up so no big deal
-tires are coming Friday. Hopefully install next week. Thatís a lot of tire money for all 9. I went back to the original size to gain those few mph back over the 225/70.
Cheers! Happy camping (and happy fixing)
David

Has anyone ever carried a motorcycle at the back of their 345? I have a hitch mounted carrier. The carrier weighs about 75lbs and the bike 310lbs.

My hitch does not look like it was modified but also it is not the simple hitch attached to the back cross member only, it is attached to a big cross member just fed of the bumper and has a single big brace going forward and up to the next cross member. (Iíll post a picture later)

Thanks!

David

I have a versihaul hitch for a motor scooter, about 300 lb. After a few trips, I decided to add some bracing to the hitch and re paint, re-mounting the receiver with grade 8 hardware. It may flex, but it ainít going to fall off!

You are talking about ~400 # tongue weight which relates to ~4000 # trailer weight, plus the effects of the weight extension. These Classics supposedly have a towing capacity of 2k#

>>>Towing capacity vs tongue weight

Weigh Safe Ė as well as most experts agree Ė that an acceptable tongue weight for any trailer is somewhere between 9 to 15 percent of the gross trailer weight (GTW). Therefore, if you are towing a 5000 lbs trailer, the tongue weight should be measured at approximately 500 lbs.<<<


Beef it up!

Why not just get one of the haulers like the Hitch-Helper?

They attach directly to the hitch and actually increase the tow capacity like a slimp dolly.

That is a very cool carrier!
I will be able to take pictures of my hitch tomorrow. The hitch looks solid but I was wondering about frame flex.


On another note, anyone has a part number for the thermo expansion valve (txV) for the AC?

P30 chassis manual says it was provided by coach builder so they donít list a PN.

Iím replacing the compressor, dryer accumulator, and TxV. I am told the txV is the main issue but these old compressors tend to leak anyway so for the cost of a charge of Freon I could get a new one.

Cant help you with the TxV. I tried so hard getting that fitting to come loose so I could replace the hose to no avail. My leak ended up being in the high Pressure hose, going from the compressor to the condenser. You may want to replace that one. My charge has been holding for 3 month now.

Looks a lot like the expansion valve listed on Rockauto.com for our chassis

1988 345... The adventure begins!

I couldnít find anything for the 87 as they only list the orifice tube after 86. I should have checked other years, I suppose GM delivered the chassis without the expansion valve and evaporator installed and Airstream went back to GM partsí bin for it! I ordered the rest of my AC parts from them! Thanks!

That is handy information. I have had trouble with my dash air leaking down for 10 years, even after I've replaced all of the components.
On another note are the stickers on your propane tank access door legible? If so, could you please post o picture of them. I'm having new ones made for my 1987 345 and can make them out. Thanks, Kenneth

Airstream Motor Home

I read some but not all of this thread.
Roby 446 has the best looking Aistream Motorhome ever built. We looked and only found gas powered ones before we bought ours. We found the gas powered ones used all their power to move themselves around, No power left for towing.
We did find a 35' Land Yacht with a Cummins 230 Turbor Diesel and a heavy duty hitch to tow what ever we wanted to up to 5000 lbs. We use a weight distribution hitch when we tow a aluminum car trailer and a anti sway bar when
it's a loaded trailer. A Blue OX tow bar for flat towing our 2006 Saturn Vue.
We still get 11 MPG at 70 MPH.
All soon to be For Sale. After 32 years of class A motor home travel, two new knees that have failed is driving us to a new life style.

Ok, back on the hitch, here are the pictures. Looks quite solid. There is a bar at the back angling up to another strong cross member. Is that stock or already stiffened you think?
Thanks!

(P.S. txV is on its way here so hopefully AC will work soon!)

Up through at least 1986 that was not stock. It look similar to what other people of done, including myself, to beef up the hitch capacity.

I was able to tow a 3500 pound race car and trailer with my 310 and the motorhome didn't even know it was back there.

Looking closer it looks like there is only one brace in the center. Most have used two diagonal braces from the center of the hitch frame forward to each chassis frame rail. I think two braces would provide better support.

The hitch you have is the same, other than the brace, as what was on my 1984 345 Motorhome. The hitch separated from the motorhome when I was towing a 14 ft. fiberglass bass boat. I had it replaced with a proper hitch with the appropriate braces by a trailer shop. After that I towed cars/trailers without any issues. I recommend you get it replaced.

New tires on! I can safely drive nowÖ
Well not exactly as I have an exhaust leakÖ. Need to pull the manifolds so maybe Iíll see how quickly I can get headers and new exhaust system.

They put very non-attractive weights on the Alcoa wheelsÖ. Not sure what should have gone there.

exhaust

The exhaust leak may be just the GM donut rings between the manifold and the exhaust pipes on the 454.Common problem. Take it to a reputable exhaust shop should fix problem, if leaking at joint. Worked for my 88' 325 . Jonathan
