70 degrees F

Hi Everyone!

One thing standing between city life and even part time boondocking (long trips) is the wife's need for a reasonable comfort level. We're not talking seat cushions and TV channels - no, she is happy with a book and a slab to sit on.

The thing she keeps asking about is if the TCs we have been looking at could sustain 70 degrees (more or less) during both the coldest of winter days and the hottest summer ones.

Of course, ambient external temps are important to this question. In the cold, we'd be in the mountains in the snow, either in California or Colorado. California is more mild, so let's start with that. Think daytime temps in the 30s and 40s on cooler stormy days. Night temps are only below zero on very rare occasions, usually won't get colder than 15.

Of course, after bed time, the inside temp doesn't have to be 70, but would be nice around 50.

Summer is less of a concern, but we'll still ask. We'd be enjoying summers in the West where it's dry with temps up to probably 110-ish max.

I know the TC and its equipment make a big difference too. We are looking for a TC on the bigger end of the scale and have been considering everything from your typical Lance (but heard some people online complain about insulation in Lance) to Arctic Fox to Chalet's big triple slider. We could downsize a tad if smaller inside airspace made a huge difference.

Investing in good heating and A/C equipment is something we could do, but would be nice to know that the rig we buy isn't simply going to leak it all out. Also would want to know the impacts on long term dry camping (heaters and A/C using lots of propane/battery versus if we had a mondo solar and wind setup to keep it juiced, etc).

There's lots of angles to take on this one, but I guess the thrust of the question is is it within the realm of possibility to keep inside temps of a modern TC near 70 degrees during the day without extreme modifications?
  • Temperature reference for my Eagle Cap, night time temps in the low to mid 30's usually results in morning inside temps of around 55 with no heater running. With in minutes, the heater has us cooked out of the place.
  • Hi,

    In the coldest part of the winter (-37 C, -35 F) I was using 5400 watts of electric heat to keep my RV warm. I kept the propane furnace as a back up heating source.

    So, yes you can keep it 70 (21 C). It may require modifications of the "stock" RV to do so.

    See the thread under Full Time called Winter RV Camping

    In the summer time Air conditioning is going to require shore power, lots of generator run time, or a quite massive solar installation. I think only the first two would apply to a truck camper.
  • I only consider RV travel because I'm able to move with the seasons. I would have to be plugged in to run the ac in the summer as running a generator around the clock just isn't practical. I'm guessing that anything below 40 degrees and our 5er furnace would run non stop so in the winter we go south. I'm equipped with four 6 volt batteries and a large battery charger and generator.

    We also want it to be 70 degrees all the time. I can stay home and be comfortable by the fireplace. I dont blame her as that 50 degree talk was over long ago for me. If I gave most RV's an easy to operate in temperature range it would be 50 to 80 degrees. Outside that range and it's time to start burning lots of power.
  • Of course, after bed time, the inside temp doesn't have to be 70, but would be nice around 50.


    That is about exactly how we keep ours when boondocking in temps down to 0*. We usually turn the temp down to about 55 when traveling, but bump it back up if we stop for more than a few minutes. By the time we can make a sandwich, temps are already back up to 70.

    Summer time, we are good up to about 80* during the day as we use the fantastic fan to create a breeze. Above that and we start looking for either higher elevations for cooler temps or campgrounds with hookups so we can run the AC. Have camped in temps up to 100+* and didn't have any problems keeping the camper near 70*. Not surprising since the AC is 13,000 BTU. For comparison, my 35' wheel only had a 15,000 BTU unit and it stayed cool too.

    And while my camper is reasonably well built, it only has 1" walls, single pain glass. There are better built campers with much better insulation which would do even better.
  • I agree with smkettner, but almost any model can be made more efficient. I think most rvs are made with moderate temperature in mind.
  • If you have a place to plug in and plenty of propane, cool and heat should not be an issue.
    If you have an issue then you fix it or upgrade the system.
  • Provided you don't camp in Death Valley nor the Polar Crest, the answer is absolutely, yes. But as you mentioned, power will be the issue. You will need a generator for sustained cooling loads. Heating in a boondocking environment could be difficult without the ability to re-fuel. Larger campers typically have AC units on them large enough to cool large TT's so there is more than enough cooling capability. It will cycle frequently both in cooling and heating mode.
