Okay, it's a 2002 keystone cougar.Has this stupid toilet that has little flush and water levers just under the seat. No foot pedals.I'm hard piped into the sewer system of the CG, Not moving the camper anytime soon this year.Can I replace the commode with a regular house tank and bowl?I am retired foreman from construction , so tools /knowhow are not a problem. Framing, plumbing it no trouble. I know I will still have a holding tank to empty when it gets full,but is there any "RV" reason a house bowl won't work??thanks

Check your rough in.Normal house 12". You can get 10" and I think 14" sp. order from some manufacturers.Or just get a upgraded porcelain RV with foot flush and spray nozzle.

You could probably do it, but do you have the room? Most porcelain toilets sit further forward or further out from the wall than a MH toiled does due to the water bowl behind the toilet. This would cut into what little floor space you have in the bathroom.When you do move it, I'd drain the porcelain toilet water tank. House hold toilet tanks are meant to sit still. When you go down the road with all of the water weight moving around in the tank, water could slosh over the top or the tank, or break off those four little bolts holding the tank to base. They're only meant to provide a tight seal between the tank and base. If the break the tank the toilet is out of commission and you have 4 (?) gallons of water all over the floor?Bill

I replaced mine with the Dometic 310 this year, not a bad lil' crapper!Red Green: They say necessity is the mother of invention. Don't know who the father is; probably remorse.

Probably have to cut a hole in the floor to get it further from the wall because of the water tank.On edit I see other poster's have brought this up.

your biggest issue is the holding tank...the only way to use a household toilet, without worrying about the tank clogging, is to remove the tank and plumb toilet straight to the sewer connection.

I will look into a better RV style one.
I will just have to get over the fact of the price of RV
stuff vs. what I'm used to paying wholesale for in the construction
business.

Check an RV salvage yard. Might find one from a newer RV that could be had for cheap.

The porcelain Dometic 320 is what we have in the truck camper and it is really nice. The FW has a Thetford Aqua-Magic V which is kinda flimsy.

Amazon.com has a really good price on the Dometic 320 series toilet.

Something else to consider. If it is a tank type it would have to be emptied every time you move. I don't think there would be enough water flow in the trailer to ever run a diaphragm type either. They need a lot of water to actuate them. I still think a newer style RV would be the best

It is feasable but less than desireable.
It will use alot of water. and if you leave the valve open to the sewer?
You will get the mound from hell in your tank from the liquids draining out.
A rv holding tank is just that, designed hold until reasonably full and then drained.

Just get a Dometic 320 and be done with it imho.

I must be missing something. Please explain why the tank would be more apt to clog with a house type toilet over an RV type.

We just went from a TT with a cheap plastic toilet just like yours to a 5er with a NICE porcelain toilet. What a difference! Foot flush is great and so much nicer to use
