Another Model 300 owner here. Last trip out we had some odor issues, but after dumping the tank they went away, so I didn't think much of it until stumbling across this thread.

So I called Dometic Sanitation @ 800-321-9886, spoke to Karen, and my new Model 310 toilet ships today, 2 day ground, will have by Friday.

I purchased a 2003 29rlbs about 18 months ago. I did everything to try and eliminate the odor. Finally I followed my nose to the source underneath the lavatory. There are two breather pipes that terminate with a slotted top. I put plastic wrap around the one with the odor and it is gone. I remove the plastic when dumping.

After reading this thread I went out and yup - we have a 300 model too. Explains why despite many cleanings it still smells.

I talked to Dometic and they referred me to Sealander 1-800-321-9886 as noted by Force above. They are replacing my 300 with the porcelain 310 at NO COST TO ME and shipping direct to our house. We will have it Friday. She even told me that the 300's trap urine in them. Told me to just throw out the other one.

Some one should make a sticky about this issue.....

I first called my dealer and the service dept. didn't have a clue about the 300 toilets. Hoping a call to Dometic first thing Monday AM will get the ball rolling with an overnight replacement as we are headed down to Myrtle Beach on Thursday for five days.

This morning I removed the 300 toilet because you couldn't stand to be in the TT. Sure enough, when I flipped it over out in the woods about a pint of yellow foul smelling waste drained out from the top. BTW: I wouldn't recommend draining this stuff in your driveway :-( Will post results of Dometic's response in a few days.
I was able to reach Diane at Dometic early Monday. She must like her job despite having to deal with disgruntled toilet owners. She's very cheerful and went the extra mile to express ship a replacement 310 in-time for our trip later in the week. It arrived on-schedule and in about 20 mins. it was up and running. It feels a lot better than the 300 as the bowl is porcelain and not rickety plastic. It worked fine over our five day beach trip to Myrtle Beach SP over Labor Day. I agree with the line of reasoning that Dometic/Forest River should be pro-active on this instead of forcing customers to waste their time trying to 1) identify the problem and; 2) figure out how to get it fixed. Thank God for this forum/thread!!

Didn't think I had any problems since the camper is brand new, but after using the trailer one time when we got back I stuck my head near the toilet and smelled what everyone else has mentioned. Talked to Diane also and got my replacement in two days. She was great to deal with and was really expecting some type of hassle but this was the best experience I have had with a company on a warranty issue. Got the new 310 installed and when I took out the old 300 I could hear the water sloshing around in it, so be careful when handling it. The new one is much sturdier than the old one. If it hadn't been for this thread wouldn't have known about this problem/fix.

Just wanted to chime in ad thank everyone for this thread! Took our first trip in our new 2014 Grey Wolf 26bh over Labor Day weekend. Got home, and a few days later went into the camper and it smelled like a litter box. Traced the smell back to the rear of the toilet. Thinking there was some kind of venting problem, I came online to research the problem, and found this thread. That was on Friday night. Called Dometic today, spoke to Heidi, and a new 310 will be delivered tomorrow! Just needed the serial number from the loo. Surprisingly she didn't want the stinky one back, said it could be recycled.

For what it's worth, our trailer was manufactured in March 2013, so hopefully they're not still putting this model toilet in new campers...

Thanks again!
