Evening folks! After a bit of help / guidance. What porta toilet is everyone typically going for now? The thetford 165 335 or 365? Been away with van today and think time to get a portable toilet is now! Daughter went 4 times before beach! From what I can see the thetford 365 has fancier flush system than 165. Also see the 335 mentioned quite a bit here. Is it worth the extra £30 to buy the 365 compared to 165? Many thanks.
