Question:
I have a 2014 Nexus Viper 29V motor home and was looking at toilets. When I tried to look up my RV I couldn’t find the Nexus manufacturer. Please include Nexus as a RV manufacturer. Also you sell the Dometic 420 but not the shorter version 421 which is what I’m interested in. Thanks Ron Ruedin

Hey Ronald, thanks for reaching out. Yes, we do carry the Dometic 420 standard height RV toilet. Here are the options we offer:
- Dometic 420 RV Toilet - Standard Height - Elongated Bowl - White Porcelain # DMC67JF
- Dometic 420 RV Toilet - Standard Height - Elongated Bowl - Tan Porcelain # DMC77JF
RV toilets aren't year, make and model specific to the RV, so there really isn't a way to use our fit guide to find the right one anyway. The most important thing is to look at the rough-in measurement, and the overall dimensions to make sure the toilet will fit in your bathroom space. The Dometic 420 RV Toilet has a 7-5/8" rough-in and measures 19" deep x 19-1/2" tall x 15" wide overall. I suggest measuring the current toilet to make sure this matches. As long as you have room for the 420 toilet, you'll be good to go.
What other bathroom upgrades are you planning for your 2014 Nexus Viper 29V?
