[frank4711]

Wanting to move up from Dometic 300 to 320 .... anyone put one in there Rockwood Ultra lite 2898KS or similar 5th wheel... where the back of the 300 is in the corner... the base is the same on the 2 toilets but the elongated bowl extends to the rear toward the wall/corner when I measure looks like the back right (looking toward the rear) may just touch the wall... the needed clearance is 2 1/2 inches and it is clear from the center to left side there is plenty but tight on the right ... anyone actually done it... Thanks for any help ... bathrooms look the same on floor-plans for the 2650WS, 2881WS. 2888WS, 2881S, 2889WS, 2891BH, 2892RB, 2896MB ... Thanks

Ordered the 310 ... installing this weekend we will see, thinking 310 will be better fit.

I swapped the 300 for a 320 in my Salem 27RLSS. Mine sits in the corner of the throne room and the 320 just touches the wall in one side, where the 300 had a little over an inch of clearance.
This was the best upgrade to my camper I have made.
