The Operators Manual says not to tow anything over 1,000 pounds.
Yet toads are towed. Are there necessary mods for this?
Where should I look for the dreaded frame rust?
What's the deal with the two tanks one filler setup?
I seem to have 3 water inlets - One in the power cord bay and two others...I get that one's gravity fill for the potable tank and one's a city water hookup - what's the third? I didn't see a third in the manual.
More - I'm sure - as I get deeper into it :~)

I too have a third water connection. It's on the drivers side below the galley window and was plumbed into the sink drain. I never was sure what its purpose was other than to perhaps flush the sewer tank.
One owner tows an enclosed 24 foot box trailer with bodatious restored Chevy inside. He says it weight about 7000 lb. I know of no mods necessary to enable this kind of tow other than a frame hitch.
The one fuel filler feeds both tanks through a T. Sometimes it works, sometime not. Venting while filling seems to be an ongoing problem often preventing the tanks from filling completely.
There was a recent post here showing many Craig's listings of GMC's for sale if you want to look around.

Towds are different from trailers as they do not really have tongue weight. BUT, I think the 1000lb limit had more to do with brakes than anything else. Toad brakes are a good thing and you should have them on any towd... especially when much over 2000lbs.
3 water inlets: I suspect you have found a PO (Previous Owner) added feature.

Peter,
You can pull anything for so long before you'll pay the price.
3.07 on a tire size that we run does not work without stressing the
transmission and lugging the engine. The Torque of the engine does not kick
in till your going 65-70.
Even the final drive takes a beating with the load from the high torque
engine.
We have supplied almost 3,000 customers with 3.55/3.70 and 12 with4.10 gear
assembly.
They tell us that the gears were the only item they found that gave them
more power without sacrificing on mileage.
I personally run a 540 Cad and find that we do best with a 3.70. I use to
run 3.55, but feel the lower ratio is lot better when we run slow speeds
around 50-60.
Back in 1982 I ran a 3.21 and hardly noticed any gain.

Of course Jim is kidding. He never runs that speed except when he is accelerating to his normal 80-85 mph. I know. Ran 1000 miles with him. Only time he ran less than 75-80 mph was when I was in the lead and hogging center line so he could not pass. Grace thanked me over and over.
