New Greyhawk Owner

What will i need as far as power requirements at a campsite, 30 amp or 50 amp? Also, what is up wit the tankless WH? Are they really as bad as what I have been reading? I will be picking up my new Greyhawk Saturday and will be going on a 10 day trip at the end of June.

Its 30 amp.

The tankless works well if you're not boondocking and you take the time to understand how it actually works. If you're camping w/o hookups, its flat out awful.

30 amp, be sure you buy an electric extension for your rig. More often than not, we aren't that close to the hookups and an electric extension is necessary. We have used the tankless water heater for almost a year now with really no issues (both with/without campsite hookup). Plenty of posts online about how to best use the system, but once you find the proper temp on thermostat vs water temp/pressure - leave it. Remember < water flow at faucet > temp.

Congrats on the new rig! Good luck with the water heater. It's very temperamental and inconsistent, in my opinion. Hopefully you will be one of the few that are satisfied with it.

Cheers!

We have found that in using the unlimited hot water tank, it's best to "turn the switch on, set the hot water temp to your comfort on the hot water side only, and use just the hot water side in a shower". Otherwise you may end up scoulding yourself.

Don't forget a water line pressure control unit to keep the pressure under forty pounds just in case the campground pressure is too high. A simple electric testing unit, to make sure the electric service is correct. Carry some leveling blocks (small plastic blocks are light) to help level the stabilizers. I purchased a 50 amp to 30 amp dog bone just in case the need ever came up. Extra drinking water hose (you never know). A back-water preventer to deal with the black water tank spray unit.

Simple things that will keep you out of trouble. Congratulations on your purchase.

I forgot to mention. Make sure you have enough dump hose. Not all campgrounds have a dump right at the coach.

If you are like us, you will enjoy "Camp Driveway". We learned a lot about overnight camping without services (just one battery).

Heck, we are still learning .....

Under 40? I keep mine around 50-52 and have never had any problems.

As I understand it .... Jayco builds their plumbing for a water pressure under 50 lbs.... That is what I was told by my dealer anyway .....!!!

Congrats

Congrats on the new Greyhawk.

As others have mentioned you are definetly 30 amp. But campground posts have a couple of notorious issues. One is placement, state / provincial parks often require an extra 50 feet of extension (sometimes more) so make sure you buy an extra 30 amp cord.

Posts are also poorly wired or connected to systems with flaws so make sure you buy a surge protector to put between your rig and the post. There are some very good quality ones that mount permanently in the RV but for under a hundred bucks you can get one that plugs in between the cord and the post.

And finally as someone mentioned get a 30 amp to 50 amp dogbone for a couple of reasons. One there are sites out there which only have 50 amp service so you want to be prepared. But more importantly if you have 50 amp available I always choose it over the 30 amp connection. The reason being many 30 amp breakers at the posts are actually providing significantly less draw and during peak power consumption periods it is not unusual to pop the breaker at the post The 50 amp connection should always allow you do draw your maximum load.

Look forward to seeing you on the road!!!
