The week before Christmas we delivered 27 boxes of cookies to businesses that we work with whether personally or for the truck, also to the businesses that have given us permission to setup, and for the owners of the country's oldest Turkey farm. Today, wife and I ran some errands and made some stops at a couple of the places we dropped off cookies. The one was the propane shop that's been helping us and where we'll fill up the tanks when need. A concern came up after I left dropping off cookies as they had a chart on the desk regarding the vaporization of LP at various tank sizes and temps.
We have 2 40lb tanks, and at 70F drawing 160K BTU, we can use those tanks for almost 11 hours. As the temp decreases the vaporization rate drops off drastically. If we were to switch to 100lb tanks, we'd be ok down to 0F, but that add 360lbs to the tongue of the trailer, interferes with the solar panel, and no good way to fasten them in place. The only solution that will work will be 120VAC thermal blankets made for those tanks. The plan would be to keep the tanks warm while the trailer is at the house and plugged into shore power. When we drop shore power and hook up the truck, they can continue to run with the extra power from the truck keeping the batteries topped off. If everything goes as plan, the heaters will only need to maintain the temp, not warm them up to temp, so they won't draw too much power. 2 Blankets, 240W total. We' only need to use them when temp gets below 35F.
We got notified today that our application has been tentatively approved by the Dept of Ag, and now we just need our opening inspection and we're open for business. Our first official date will probably be Jan 15th at a local gun shop that has a large manufacturing facility as their neighbor. Good visibility from the road, lots of parking available. We'll have space to put some signs by the road.
We bought the trailer on Feb 17th 2023, and we're opening about 11 months later.
