When it comes to road trips, camping, or RV life, one truth reigns supreme: nature calls, no matter where you are. Enter the Thetford Porta-Potti series—the kings (and queens) of portable porcelain. But with so many models to choose from, how do you know which plastic palace is right for your, uh… royal duties?

Let’s break it down.

Porta-Potti 135 – The “Compact King” 

• Size: Small, light, and easy to carry.

• Best for: Tent campers, van lifers, and anyone short on space.

• Why you’ll love it: It’s the ultimate “grab-and-go” throne. Think of it as the porta-potty equivalent of a folding stool—simple, no-frills, gets the job done.

Porta-Potti 335 – The “Marine Monarch”

• Size: Still compact, but with a built-in hold-down kit.

• Best for: Boats, small RVs, and bumpy rides where you don’t want your toilet sliding into the sunset.

• Why you’ll love it: Stability! It stays put, even when you hit a wave or a pothole.

Porta-Potti 345 – The “Middleweight Champ”

• Size: A little larger, with more fresh-water capacity.

• Best for: Weekend warriors who camp a few days at a time.

• Why you’ll love it: Big enough for comfort, small enough not to hog storage space. It’s the Goldilocks of portable toilets.

Porta-Potti 365 – The “Family Favorite”

• Size: Larger tank = fewer trips to the dump station.

• Best for: Families, groups, or longer adventures.

• Why you’ll love it: Comfortable height and generous capacity—finally, a seat everyone fights to use, not avoid.

Porta-Potti 565E – The “Luxury Throne”

• Size: Full-size design, battery-powered flush.

• Best for: RVers who want a toilet that feels like home.

• Why you’ll love it: It’s got curves, comfort, and an electric flush. Basically, it’s the Cadillac of portable commodes.
