166FBS 2021 Jay Feather Micro Glacier Package

linmicsar · 02-10-2023, 01:21 PM

We are taking our Jayco into cold Northern AZ Weather with nighttime lows below freezing 19 to 34 degrees. Daytime high 40s to low 50s.

Can anyone explain how our Glacier Package is beneficial? How is our furnace duct work laid out? Does is surround our water tank and is the insulation in our underbelly worth anything? I talked to a technician, and he said one doesn't know whether or not the insulation was installed evenly or tossed in landing on one side or the other.

Thank You,
Linda

The "Glacier Package" is just the underbelly enclosure. It probably keeps some heat in, but does not include anything to heat the area. Likewise, the furnace output is strictly into the cabin, none down to the tanks.

Jayco offers optional tank heaters. 110V pads that are stuck the bottom of the tanks. If you have that option, there will be a red switch just inside the door, on the sidewall of the kitchen sink. As stated, they are 110V, so only available when you have power. One further cautionary note: The switch will light up when on, whether there is power or not. On mine, the heaters were actually unplugged, which I discovered by accident. The plugs are down below the bottom drawer, under the stovetop. Same place as the water pump.

Those who do extensive winter camping will often also wrap hoses and drain pipes with heat tape.

While I'm thinking about it, I should mention I've never seen a Micro with insulation above the underbelly covering, at least not from the factory, thrown in or otherwise.

That’s disappointing. I found a YouTube that details the Glacier Package. The Camping Advisor RVING 101. This blogger said that Jayco only states that the underbelly is enclosed. Yet, this blogger says it should have a smaller heating duct directed to our tank and pipes. It should have extra insulation added to our underbelly. That extra insulation could be a sheet of corrugated plastic or some foam spray. The under belly is sealed. Bad news is what the technician said. Inferior installation could make it useless. It should withstand temperatures easily between 15 and 50 degrees. If installed correctly, our pipes and tanks should be protected down to about 0 degrees. I guess this blog is BS?

DonBr · 02-10-2023, 11:49 PM

I can only answer with certainty about my Micro, and others I've seen with the underbelly cut for various reasons such as repair of the rather weak supports for the water tank. Keep in mind that Jayco makes a lot of models - did they reference any model in the blog?

I can pretty much guarantee that the Glacier on a Micro is only the underbelly, but that is, indeed, corrugated plastic. Also, having had my heater out, I can guarantee that it blows only into the cabin.

Do you have the tank heater option?

My 2016 has the Thermal package which was advertised as having a heated underbelly via a furnace duct but I've checked and it does not exist. It was a blatant lie.

linmicsar · 02-11-2023, 10:11 AM

The blogger stated that the Glacier package is an add-on feature with varying degrees of materials involved. He clearly stated that the Glacier Package “should “ include extra insulation, some plastic materials to seal the underbelly, and an additional heating duct installed. He said Arctic, Polar, and Glacier packages are all the same. He said installation is the key and this statement is in line with what the Jayco technician told me. It sounds like this package could be a crapshoot between what should be installed and what is installed. I plan to contact the sales manager for selling this add-on claiming 4 season camping. I am really annoyed because this is so deceptive and confusing. It is or isn’t 4 season should be a simple yes or no. Thanks for your input guys! It’s been very helpful.

Good to know! Thanks.

DonBr · 02-11-2023, 10:30 AM

A minor clarification: The glacier package is/was standard, not an add-on. It is part of the JayPro mandatory package, and is worded "Glacier Package includes enclosed underbelly."

linmicsar · 02-13-2023, 11:15 PM

Below is the response from a Jayco Company Service Representative. The Sales Manager from Camping World provided the Specs for my unit that lists the “Glacier Package” in the Jayco Pro Option bundle and there is a Glacier Package emblem on my unit.
Jayco response starts below.

Good Afternoon,

Thank you for contacting Jayco Customer Service.

There is not a glacier package available for this unit. So there is not Glacier package on this unit. Also none of the products that Jayco manufactures that the water system can be used in below 32 degrees.

DonBr · 02-14-2023, 01:02 AM

What absurdity! They must outsource support to the lowest bidder. We know the facts: The JayPro "Option" is not an option, it is mandatory with all Micros; It includes the Glacier package, and all of us have the sticker saying so; the specs are clear that the Glacier is just the underbelly enclosure.

Now, as to the below 32 not being supported that is again untrue. Some higher-end Jayco products have extensive underbelly heating. In the case of the Micros, there is the option (and it is truly an option) to have heat pads on the tanks. I have that option, although I haven't had occasion to use it.

So, you asked, and got a nonsensical answer, but the real answers were already here.

Good Morning,

The information I have on file is not showing that as an option. Depending on the when your unit was manufactured. Jayco has added that package to Jay Pro Package. You do have the glacier package based off your MSRP. The glacier package on your unit comes with an comes with added insulation and ducting to the underbelly and an enclosed underbelly. Jayco still does not recommend using your water system in below 32 degrees.

I feel pretty confident that my RV will withstand overnight temps at around 25-34 degrees with the furnace running at around 55 degrees. Wish us luck on our ATV tour down to Lake Mead and our adventures hiking in the Joshua Tree Forest and exploring the Grand Canyon West Entrance in our RV with a Glacier Package.

Wow, I’m not sure I’d gamble my RV on two near-illiterate responses from customer service “specialists.” But good luck!

We live in AZ as well and have the same trailer. Having had opportunities to basically be in and look at what I think is every crack and crevice on it I can say that there ARE some "ducts" to the underbelly. If you want to call them that...

The first is over the fresh water tank. It is under the bottom drawer under the stove, same place the 110v plugs are for the tank heaters. This is also where the water pump is. You will see a decent hole cut in the floor and that is the top of the fresh water tank.

If I remember correctly I believe there is also a hole (smaller) under the shower that would allow some air into the grey and black tank area.

Other than the tanks all other piping is inside the trailer living space and shouldn't be a problem.

We have camped in the Flagstaff and Payson areas when the low got in the single digits. We had no issues. Just remember to keep the heater on and if you have power I would keep the tank heaters on as well. They are thermostat controlled on their own and will turn off if its warm enough and on when its cold.. Good thing is most times here in AZ its much warmer during the day so things stay good. I dont know if I would call these 4 season but definitely a 3+/extended season trailer.

We stay much warmer than our friends do in their trailers, I can say that.

I wouldn't. defies the common theme that heat rises. "Ducting" would normally mean from the heater, and I do think that there are several higher-end Jayco products that have such ducting, just not the Micros.

Thats why the word "duct" was in quotes! :-) But it does, at least on ours, have a gap around that hole which would allow for air to come in/out. It is for sure not air tight!

Could mount some fans on there to blow heat/air down into the belly of the beast!

To that point I have not seen ANY ducting directly from the heater into the belly.. That just does not exist on the micros.

This is true, and not a lot more difficult than other mods we've done, although I would probably go further and make a bigger hole for the fan to blow through.

Maybe they called it the Glacier Pkg. because if it gets cold, things will freeze like a rock��.

Toad · 02-18-2023, 01:58 PM

Beautiful area up north Arizona especially in the Rim country.

Traveled there many times in winter with RV.

Pointers...
Our Propane furnace is under couch in our 232RBW, 2 air ducts to heat inside trailer but nothing heating the enclosed underbelly.

Spliced one heat duct line cut hole in floor under couch, added an air duct blowing into underbelly. Worked perfectly to heat underbelly.

Ours is the Rocky Mountain Edition "doesn't mean much" just enclosed underbelly.

Keep fresh water tank at least 1/4 full "takes a lot to freeze that much water."

Freeze tape for outdoor plumbing lines.

Keep inside door open where outdoor shower is to keep that area from freezing from outside.

Beyond that, never had issues.

Happy traveling...;0)
