Bathroom Remodel Question ~> Full size tub/shower combo?

Regarding how many times I'd have to dump my 36 gallon Gray Tank #2 (Wash tank) When I'm on a full hook up site I drain it via a 3/4" GRAY garden hose and leave the valve open, this is the ONLY tank where I leave the dump valve open, the hose forms a natural water trap so sewer gas does not migrate out of the ground into my RV via this path. So i'd only dump once a week, all week, from 12:00:01AM on the first day to .. Well the start of the next week.

But more important.... I have a six gallon water heater, With a couple tricks I can kick it up to 10 or the equivalent of 10, but how many gallons of HOT do I need to fill that tub? (More I suspect) I'd need a flash heater for the tub.

I'd be concerned about the weight. Not of the plastic tub, the water. At 8.3 pounds per gallon, you could wind up soaking under your RV instead of in it. That's not only expensive, its embarrassing. :)
My parents were RVers. After many years and miles, they decided to swap their 'C' for a park model in Florida. They're designed to support a shower/tub combo because they sit on a concrete slab and have a full size water heater. Sure made my Mom happy.

I think, Few people will be interested to use the shower combo in their RV's. You have mentioned the tank less water heater. So, Could you please tell me the model or type of the water heater. Sometimes, The choice of water heater type will be helpful regarding for the fixation of shower combo in RV's.

We also put in prior a tank less water heater. So, we now have plenty of hot water to fill a big tub ;)

Have you used the tank less water heater? Gas or Electric? Model? Reviews give mixed reports. How do you like yours?
Thanks

Just food for thought - how many times would you have to dump the grey tank in a weeks time if you used a HUGE bath tub??????

and how will you be using your RV? For the occasional summer trip, full timing? For anything besides full timing I'd prolly just book a spa day from time to time, LOL.

Currently, our RV has a bath tub combo, but just smaller :/ It's big enough for my younger child to take a bath, but not me. As a woman, I miss my baths! lol ;)

We haven't used the bathtubs in our S&B in the 15 years we've lived here, except when young grandchildren visit. Our Class A just has a shower stall, and though a little bigger would be desirable, we haven't felt the need for anything else.
