What is the Jayco thermal package?

In this blog post, we will answer the following question: What is the Jayco thermal package? We will explain the benefits of a Jayco thermal package and give you a few essential tips to prepare your Jayco RV for winter days. 

What is the Jayco thermal package?

The Jayco thermal package is an optional package that can be added to almost any Jayco RV model. Here are the benefits of a Jayco thermal package:

  • It warrants a closed, insulated and heated bottom;
  • Two-sided reflective insulation sheet on main roof and sliding room floors;
  • Heated underbelly that prevents water freezing;
  • Dual-pane windows;
  • Higher wall, floor and roof insulation.

Besides the Jayco thermal package, the manufacturers also offer the following option: Climate Shield

Climate Shield basically guarantees warm and safe travels, due to the following four major highlights:  

  1. G20 tint windows to protect you from strong UV rays;
  2. Double-sided “Radiant Barrier” insulation that will keep all the heat inside;
  3. Heated underbelly that will prevent the water tanks and the sewage tank from freezing;
  4. PEX-tested plumbing that will resist even at -40 degrees Fahrenheit.

Why should you opt for the Jayco thermal package?

The reason why a Jayco thermal package is a good option is that an RV with a thermal package is simply better isolated, thus it’s warmer! For many, the winter RV is a dilemma between turning up the heat and therefore using your precious fuel or staying frozen.

The truth is, most RVs aren’t made for the cold, and the ones that are aren’t usually cheap. Older RVs tend to have less efficient insulation and heating mechanisms. So even if you turn the heat on, you will see your heating expenses leaking from any leaks and cracks your RV might have. 

An RV that has a thermal package promises higher insulation and warmer days. Plus, you will save so much electricity (to be read “money”) since you won’t have to use your RV’s boiler, AC or heater pump. 

Travelling in an RV during winter: essential tips

The winter period has some peculiarities that imply a revision of practically all the motor and housing elements of our RV or camper. Although this will be a different winter, it is advisable to have our vehicle ready for any getaways that arise. We delve into all the items that we must have under control to enjoy our trips during the winter without incident.

Preparing the exterior of the RV for winter trips

The exterior of our vehicle is the most exposed to weather conditions, therefore, we must take a series of preventive measures to avoid suffering the consequences of frost:

  • Pour antifreeze into the drains of the different pipes; washbasin, sink and shower to prevent dirty water from freezing. In fact, the best measure is to carry out an in-depth review of the entire water system of the motorhome or camper, including our WC.
  • Lubricate all exterior locks and hinges to prevent freezing. If they announce the risk of significant frost, protect the locks with electrical tape to prevent the entry of water or snow that freezes inside.
  • Put a little grease or petroleum jelly on the cylinder of the door locks to prevent the locks from freezing
  • Wear chains and check the pressure and condition of the tires, as well as the levels of antifreeze, brake fluid and oil. Another good option is to use winter tires, which are more recommended for heavy vehicles such as motorhomes or large volume campers.
  • Use cleaning fluid for the windscreen wiper blades to protect their surface.
  • Protect the outer grates of the refrigerator by placing the so-called winter covers.
  • Check the vehicle’s lights, which means using bulbs that provide good visibility in snowy and rainy conditions.
  • Check the electrolyte level of the starter battery and clean its terminals.

Preparing the interior of the RV for winter trips

Within our housing module we must be aware of carrying out an exhaustive control of the following elements:

  • Have propane cylinders, not butane, since below zero degrees it freezes and have the gas checked by our specialized supplier.
  • Change the battery if you think the old one is not in good condition. A more suitable option is to install a second auxiliary battery to have complete electrical autonomy. Do you know which is the battery that best suits your needs?
  • Have special protections for cold in the skylights, as well as isothermal blinds in all the windows.
  • Review the correct operation of our heating in advance to solve possible incidents.
  • Although this measure is necessary throughout the year, we must be especially aware of having vents inside the vehicle for safety, but above all to avoid condensation itself due to the difference in temperatures inside and outside the RV or camper.

Should I cover my RV in winter?

Yes, you should cover your RV in winter with good quality, breathable and light RV cover. A caravan with a protective cover can be safely stored inside and outside, no matter the season, but especially in winter. 

An RV cover has many advantages, but these are the most important ones:

  • The RV stays dry no matter the weather;
  • The RV is protected against dirt, dust and UV rays;
  • The protective cover consists of several layers in order to protect the RV as well as possible from any possible damage;
  • An RV kept well has a much higher resale price.

By covering the vehicle, you will have the satisfaction of finding it clean in the spring and you will only have to carry out small annual maintenance work before setting off again on the roads.

The bottom line

If you are planning to travel in an RV this winter, dress warmly and tackle the cold effectively with these tips. Their application will guarantee you comfort onboard your vehicle and will make sure that you will enjoy your winter trips more!
