Hi, just wondering if this is the smallest Thetford available? I have very limited space in my van and wanted to get the smallest possible Thetford porta potti. Thanks.

Given that the 335 is 3.2 kg empty, when filled with 20 litres of water (10 holding, 10 flushing), can you give me that weight? If stored in one of your bags, I'd like to know portability from the back of a campervan to the front for overnight usage. Oh - the maximum height for storage is 33 cm.

Can the larger capacity waste tank of a 365 be used with a 335? I have a 335, but want to know if I can increase waste tank capacity.

Hi, I would like to know whether the seat on the Thetford 335 is the same size or smaller than then one on the Thetford 345? Thanks

Okay, so I have 4WD wagon & the only place I can keep this while travelling is in the back of the car. No room on the roof rack, as we have a roof top tent & we don't tow a trailer. So the question is.......do they smell when they are stored & in transit between camp sites??
