RV Toilet Removal- PVC Test Plugs?

[DebtFreeRVing]

Hi, guys!

I'm going to remove our RV toilet (and not replace it- we're done w/black tanks and decided to use a Thetford Porta Potti). Is a PVC test plug/cap what I should be using to cover up the sewer hole permanently aince w/out a toilet it will be left exposed? If so, is there a standard size I should be looking for? (We're in a 1992 Cobra Passport RV).

Any advice is welcome!

Thanks
