New to me 2015 Newmar 3220 info

Hi everyone! Just brought my rig home and trying to get setup for camping. I would love input on these things I need to purchase
1. 50 amp surge protector (I know Progressive is recommended). But do I really need it to be hard wired or will plug in suffice? I think I do have a gauge inside measure usage.
2. Water hose supply. Need pressure regulator suggestions. Does anyone know the size of the hose? I want to purchase a flexible one and quick connects (I am not at the RV right now).
3. Do I need chocks in a Class A? Also plan on getting the Snapads…I think they are 9”???
4. Plan on getting TPMS and Viair as well.
Thanks so much for any input!

You'll probably get lots of opinions on these.

1. The previous owner had installed a 50 amp Progressive on my coach because he was concerned forgetting a portable unit on the pedestal. I thought that it would be a real pain if it blows on the road and need to get a new one. And it's inside the basement in a difficult place to get to.
So I got a Southwire 34950 Surge Guard also. With that it's easy to check the pedestal before I plug in.

2. I have several Zero-G hoses. Light and easy to handle. Just reqular garden hose.
I have Renator M11-0660R Water Pressure Regulator. Had to buy a second one as I forgot to take that out the first winter and it froze.

3. Chocks prevent vehicle from rolling. I never use any unless I need to work under the coach. Then blocs of 2x4. I use heavy plywood squares under the jacks to spread the load a bit wider. I don't believe on those snap pads. They don't increase the area much and probably have more effect in lightening your wallet.

4.I have EEZTire 10 sensor unit to cover the toad also.
There are other good ones like TST 507 and Tire Minder. It comes to the preference on the display, setup etc. as they are all basically the same. Just don't skimp on that one and try to get the cheapest unit.
I have Viair 400P-RV in the coach for on the road needs but at home I use a big compressor. Much faster.

Hello Cyndi and congrats on your Newmar purchase!

I have always used portable surge protectors with my RVs. I use the 50A Progressive that plugs right into the pedestal. I highly recommend it.

There are all kinds of options for water hoses. I have used Zero G and they work well. Just make sure that whatever you buy is a proper RV water hose that’s certified food grade/drinking water approved. I bought modular quick connect fittings on Amazon. They make setup much easier.

I don’t typically use wheel chocks with my Class A rig like I did with my Airstream trailer. You certainly can use them, but if everything in your rig is functioning properly (like the parking brake) then you should be fine without chocks in most situations. Some people use them when parked on a steeper grade than usual, and there’s nothing wrong with that. I’m a fan of Snap Pads. I used them with my Airstream and I still need to buy a set for my Newmar. You’ll need to measure your leveling jack feet to make sure you order the right size. They’re particularly nice on soft ground or gravel parking spots. They’re much easier than crawling underneath your rig to place some kind of a jack pad.

TPMS is a must, in my opinion. There are many brands out there. I’ve had good luck with TST and with Eez-Tire. I recommend flow through sensors. I’ve also had good luck with Vlair pumps. You can’t go wrong with Vlair.

Good luck and post some pics of your new rig!

Newmar Accessories

We have a 2022 Newmar MH 35', previously had an Arctic Fox 5th wheel for a decade and used all manner of accessories. Combined, have traveled more than 70K miles.

** Currently use Air Stream no kink water houses, they are coiled, light weight and if pressed can stretch almost 40', although we are usually in the 20'-30' range. We bought white for potable and blue for grey tanks. They may have shorter lengths. Not cheap but work. Use quick connectors on all hoses and filters, including RV connections.

** We use Progressive EMS-PT50X Surge Protector. Prefer portable, just my preference. Not cheap and they have less expensive without EMS. I have short cable for securing to pedestal. Does it work - Don't know, have never had an occasion to test it's worthiness under extreme circumstances even though we've been in a number of storms with lighting and a few sketchy RV Parks.
** Use TST 507 (10 sensor) more than 5 years - On 5th wheel, MH and Ford pickup, easy to read temp and pressure on all 10 tires. Did add a signal repeater to ensure good read on toad. Does have one quark, not often but alarm occasionally sounds without reason. Read about alarm on this web site before I purchased. Non issue, actually a good reminder to check monitor.
** I don't use chocks, did for 5th wheel. MH, when parked in PARK and emergency brake on. When camping all of the above and on Leveling Jacks.
**** As you can see, many who answer are more knowledgeable and experienced than myself. Whether repairs, directions or general suggestions, this site is my go to place for help.

Some good advice already, but I’ll add a couple of comments.

A pedestal surge protector is a good practice to make sure the pedestal is wired correctly. Some good options are Progressive, Southwire and watchdog., All 3 good choices.

As mentioned, a TPMS system is critical to keep an eye on your tires. I highly recommend the TST system. The 507 which is good, but they now have a 770 version which has a larger touch screen. I upgraded to the 770 and it is much easier to setup and the larger screen is great.
