Virtual RVing (or What-To-Do-In-Winter-Before-You-Start-Fulltiming)

virtual_rving9_artsy

Though the allure of the open road ever beckons part-time RVers like Jan & I,  it’s one thing to drive around Wisconsin in the summers and quite another to drive around North America.

We’ve been part-time RVing for 10 years and have driven our motorhome down many roads, but I think full-time RVing will be a different animal — at least in scale.

With the prospect of living on the road 24 hours a day, 7 days a week, 365 days a year . . . how much driving is enough? Too much? How long should we stay at a campsite? What will it cost? Where do we go?

There’s no way of knowing for sure, but I think there’s a way of preparing for this transition . . . Virtual RV Trips !

I can’t imagine that I made this term up, but here’s what I’ve been doing over long Wisconsin Winters. Armed with an Excel spreadsheet, I started with a start and final destination and then planned a trip using actual campgrounds along the way.

After creating about a dozen of these Virtual RV Trips, I learned a few things:

  • I’d rather be taking real trips instead of virtual ones.
  • With each new Virtual RV Trip, the amount of daily driving I did kept dropping. I tended to stay longer and longer at campsites.
  • When I added the average temperature for each destination, this seemed like a good guide for both the Winter and Summer months.
  • I started to get ballpark figures for campground costs.
  • I learned a lot about campgrounds themselves . . . amenities, cost, locations, . . .

We’ll see.

Here’s a sample Virtual RV Trip . . . virtual_rving9

Fridge Fans (Internal & External)

Anyone who uses an absorption refrigerator, like our old Dometic NDR1292, knows that the hotter the weather, the less efficient these fridges operate. Basically, it gets increasingly difficult to get hard ice cream as the outside temperature rises.

Adding a fan (inside or outside a fridge) is a relatively inexpensive method of improving the performance of an absorption refrigerator.

INSIDE A FRIDGE

The purpose of adding a fan inside a refrigerator is to improve efficiency by moving the cool air around.

12V Internal Fan

I tried a 12V internal fan that I bought on eBay. This 2-fan unit draws its power from the light inside the fridge. Don’t worry, it’s connected in such as way that the fan stays on when the door closes.

This virtually silent dual-fan moves the air around pretty well.

Battery-Powered Fan

Battery-Powered Fan

Another type of internal fan just uses a battery to power its fan. These units run for a long time, but must be constantly monitored. Camping World sells them as well as other vendors.

However, while both of these internal fans worked ok, I had heard that adding an external fan to cool the refrigerator itself might work a lot better.

OUTSIDE A FRIDGE

The goal of an external fan is to cool the gas absorption unit of the refrigerator itself.

On the back of an absorption refrigerator — the business side — a cooling unit is attached to the back of the fridge.  The cooling unit works by heating a tank of ammonia which turns from a gas to a liquid. This process cools the refrigerator, but heat is generated which is supposed to be removed by the convection air flow in the back of the fridge.

However, in hot weather it becomes more and more difficult for convection alone to remove this heat.

So to improve air flow a fan can be placed either at the back of the cooling unit or at the roof vent. I added two thermally-controlled fans from www.coolerguys.com inside the roof vent. These fans turn on when the temperature reaches 88 degrees F.
