We're camped out near Huntington, UT now. Last night it got down to 20 degrees. When we went to bed, it was 60 degrees inside the trailer. When we woke up it was 48 degrees inside. We turned on the heat for 15 minutes this morning to get it back up to 60 degrees (we like it cooler, especially for sleeping). It's the first time we've run the heat in months. We generally don't try to camp in cold areas on purpose, but when we end up with cold overnight temps, we really like all that insulation. I don't think the insulation on the smaller Kingdom trailers will be as substantial as it is on the XL. When we worked with Jamin to build the first XL, we specified what each layer in the walls/roof/floor would be so we ended up with more insulation (especially by adding thermal breaks) than you typically see on a trailer. As a result, we're at 7,800 lbs dry weight (9,820 lbs GVWR). I tell people nothing less than a F250/2500 for towing an XL, but people like to push their vehicles up to 100%+ of capacity. We did finally post a blog (
RVino Blog) with pictures from some remote AZ camping. We haven't gotten around to the Mojave Preserve pictures yet.
