I really like your idea of the 15' & 35' lenghts. Make a lot of sense to me.
Our 2351D Phoenix Cruiser, Jack, has turned us from campers into RVers and loving it!

I have used both sizes and given the small size of RV plumbing haven't found the 1/2" hose limiting in volume.

Agree with your comment + others that say 1/2 is easier to handle.

I lean towards 1/2".

Whether you go 1/2" or 5/8", I'd suggest getting it 50' long, then cut it into a 15' and a 35', adding the new ends as necessary. That way, you can use only what's needed; 15', 35', or 50' (combined).

As others have said it does not make a difference in pressure or volume. What I find is the smaller dia hose kinks less, rolls up easier and takes up less space in my water compartment.

either will work but make sure you attach a pressure control guage of some sort so you don't blow your lines up

I put in 1/2" water lines and a quality pressure reducer at the hydrant.

I'm fixing to have a total knee replacement in March, so my camping will come a little later, after I've done a bunch of rehab.

I did one new knee 3 weeks ago, doing well and walking unaided. Another one in just under 3 weeks is scheduled. Good Luck, do the therapy as best you can.

Make sure you do the PRE SURGERY exercises, and follow the post surgery instructions. You can tell which friends have done what their doctors told them, as they are moving quite will a short time later. Those that didn't are months into recovery whining about how the surgery didn't go well.

Having a pressure limiting device is much more important than what sized hose.


Heed ppine's post. This can be VERY important.

I replaced the plumbing in my 75 Prowler... Frozen and busted...
Lowered the cost of purchase.
I put in 1/2" water lines and a quality pressure reducer at the hydrant.

What difference does it make? Not a lot, my inside hydrants all neck down to 3/8".

I did have the peace of mind that the previous plumbing was gone, and My plumbing did not leak.
Last Fall, I made dang sure I did everything when I winterized my trailer.
I blew out the lines, then filled them with the Pink stuff.
It will take a couple minutes to drain all the lines and run clean water thru them before I take it out this Spring.

My current favorite water hose is by "Flexzilla". This 5/8" hose stays really flexible even in sub-freezing temperatures. I carry a 3' length, a 10' length, and two 25' lengths that cover every situation I've run into so far.

For drinking no difference for showers like no difference and for filling the on board tank 5/8ths or 3/4ths

Some years ago due to an issue with the city water where I'm parked I started filling the on board and using it (There were multiple issues including 120 PSI at the faucet) Most of those issues are now resolved (I have a good regulator) but I still fill and pump.. Since wife died I can go 3-4 weeks w/o filling. I stay in two parksm Summer it's 2/weeks 2/weeks.. Winter 2/1/2/1. So I fill up just before I leave Wed. and I'm good till I get back. no need to break out a hose at the other park.

And though the hose is hooked up today.. It's full of air so freezing is not an issue if it gets cold.
Home was where I park it. but alas the.

If you want the best.....easiest to handle and rolls up super easy, Get this -
Zero G water hose

I bought one of these last year and love it! Much easier to handle and store than the white rv hoses.
