Best Upgrade for Dometic 310 Part-Timer RV Toilet

Question:

I need a bigger toilet as I am a big guy. I currently have a 2021 rockwood ultra lite 2608s. I believe its a dometic 310 almond color. The 320 probably wont fit. Is there another brand or model that will fit without modifications? Please help!

The Dometic 310 Part-Timer RV Toilet, # DOM37FR that you currently have, in tan, is a standard-height RV toilet with a ceramic bowl and slow-close lid. It is 20" tall with a seat length of 15-1/4" and seat cutout dimensions of 10-3/4" long x 8" wide.

The best option we have is only in white, the Dometic 510 Full-Timer, # DOM29FR with a deep ceramic bowl matching that of a residential toilet and having an enclosed rim to prevent splashes. This is 19-1/2" tall but has a wider base and the seat cutout is 11" long x 8" wide. This option also includes a hand sprayer that assists with cleaning.

There's one measurement you should double check to see if this toilet will easily fit into your bathroom. The rough-in measurement is the minimum distance you'll need from the wall to the center of the flange on which the toilet will sit. To measure this distance without uninstalling your current toilet, the mounting bolts on the side will typically tell you where the center of the flange is. The Dometic 510 Series RV toilet has a rough-in measurement of 11". The Dometic 310 Part-Timer RV Toilet, # DOM37FR that you currently have installed requires a rough in of no less than 10".
