I've got a 2012 Sunseeker 2900. DW and I are new to motor homing and we're having a spirited discussion regarding tankage. On our last two trips I hauled 5 gallons of fresh water and 5 gallons of black water (geo method). This gave us enough fresh water to use the facilities or do whatever we needed to do en route. This seems like common sense to me, haul as little weight as possible and distribute what you do have forward if possible. Hauling 44 gals aft of the rear axle seems wrong to me.

Can some of you pipe in with do's, dont's, and reasons why? Also, how easy is it to fill up with fresh water while on the road?

Hauling the minimum amount of water that meets your needs is good. Just be sure you can get water at your destination.

I wouldn't plan on getting water on the road. I wouldn't trust water at a gas station. I only get water a campground or at a friend's house. Others probably have different opinions.

I usually fill our fresh water tank because we often do not know where we will be staying the next night and water hook-up may not be available. I just accept the additional weight to have the flexibility of staying where we want to, not where we have to have hook-ups.

You'll figure out what's best for your style of camping and traveling.

I just fill up a couple of milk jugs of water, to keep in the bathroom. Use this water to flush toilet while traveling or over nighting at WM.

This is my method, also. We always know where we're going when we leave home and know we can get water there.

I only keep water in the tank when traveling long distances. My rule is about a third full. But then again that is if I'm traveling more than 500 miles or more than a day's journey.

We tend to run between 1/2 to full on the fresh water. We don't tow anything so the impact of 200-400 lbs of water is negligible for the V10 in our Forester. As far as the black water we try and empty before heading home and run ~10 or so gallons of water in the black tank to rinse the tank on the way home. We have a free dump station 2 miles from home so either way works for us.
Good luck.

Thanks guys, plenty to think about. I suspect I'll do what DW wants to do and fill the FW prior to our next trip, we're going to Vegas and we'll be dry camping behind Ceasars for 2 night before heading on up to Yosemite. Our only option would be to fill up at a gas station once we arrive in Vegas and she's not too excited about that... We don't drink the water but we do shower with it and that's enough. I have to agree after some of the stories about nasty water I've read here and elsewhere. Thanks again!

We do use our fresh water for cooking, coffee, flushing, washing, and keeping the dogs hydrated.
I top ours off to between 1/3rd to 1/2 full. Depending on where we are going and how long we will be on the road. The only real dry camping we do is in families driveways. I'll fill up the tank when we arrive as I'd rather use my own shower and toilet than those who we are staying with. We have 3 kids, so bringing our own space with us works out well and keeps us from becoming a burden on others.

We drive with about 5 gallons of water in the tanks (geo method for black), but we also keep two 1 gallon jugs stowed behind the toilet for flushing while on the road. That way we don't need to wonder if the water pump is on or off
