Dang, the search function didn't really help but I'm sure this has been asked and answered before. Sorry for being redundant.
Filled up the new coach (77 Eleganza II). Got it as full as I could and splashed a tiny bit out but as I was putting the nozzle back on the pump, I could hear it gurgling.
When I got back in my coach I noticed a gas smell but assumed I had stepped in a puddle. However, 100 miles later it is at home. When I backed her into the parking space and leveled her up, there is a very noticeable gas smell both inside the coach and around the engine. I lifted the cover and don't see any gas puddles on the engine.
Thoughts and suggestions please?

Had a similar experience with gas flowing from the top of my fuel tanks during a fill-up. Bottom line was my tanks had small cracks on the top of both tanks and fuel had been puddling there for quite some time. The fix was to replace both fuel tanks and install new fuel lines -- OUCH!

Similar gas smell experience once when I attempted to fill the tanks all to the top. Ended up with gas in the charcoal canister, on the passenger side of the coach.
Also had gas smell that was finally located around gas line fittings. Bad gas line, replaced with 30R stuff from NAPA. Fixed that one. Need to do rest of gas line.
Many places to look.
Gurgling or gas burbling is normal when filling gas tanks too fast. The trapped air has only one route of the tanks. I normally put about 20 gallons in, then wait for a little time, to allow trapped gas to escape, then finish filling the tanks.
Good luck, many points to look at.

Kerry,
From some very personal and direct experience, I believe that Rob has the closest answer even if it is not complete.
In my coach, the 1/2 in fill vent line that ties into the fill tube at its top that is in that lump behind the driver's left elbow was completely junk. Getting that side panel (what would be a door card if it were a car) is a real challenge. but you should embrace it an rise to it. (I only go the rear edge loose and worked through that opening.) That was most of the problem. The other (and still is sort of a problem) is the seal around the fill neck in its hidy-hole. The fill neck was pop riveted to the body and is loose now because what ever bedding was used is long gone. This means that any spill at the fill neck ends up in the cab. This is notable, but it does not linger. I have tried several new sealants and most could be removed in toto (yes, with the dog) after a subsequent fill.
So, replace the 1/2 fill vent hose all the way to the metal of the fill neck, and if you find a sealant that is still solid after the second fill, let us know.
By the way. if you are re-running the fill vent lines, move the T up to the cab floor. A lot of those problems go away.
