Waste tanks can be upgraded to have wheels
Thetford introduced Toilet Fresh-Up Set for the C200 and C2/C3/C4 with the waste-holding tanks on wheels at the beginning of 2015. Since then Thetford has redesigned their Cassette tank for the C234 and C200 with wheels and handle which means that all their tanks can now be upgraded to have wheels and a handle.
The new C234 and C200 tanks with wheels is available in the Thetford Fresh-up set. With this set, including a waste holding tank, Seat & Cover and additives, Thetford offers a complete package to make a 'new', personal toilet again.
