If putting it on wheels, devise a method to level it easily each time you set it up. Try to get it to have less than 1/4" off in any direction, 1/8" is even better. Maybe you can set up some sort of screw adjustable feet near each wheel. For the bricks, I second psparr. Most masonry yards will have them far cheaper than any maple supplier, and likely cheaper than any Ebay when you figure the shipping.. Read the instructions, a half pint uses a lot more bricks than you might guess. You can use half bricks (half thickness) to line the firebox, but use full bricks for the rear wall. A full brick is almost 2x as thick but is only slightly more in price. This said, I found refractory cement sometimes a better price at the maple suppliers, in larger sizes. While I've used both, I find the pre-mix easier to use, but dry , mix your own is cheaper and it does work OK.
My first season I was on a half pint, I started with 27 taps and kept adding after each sap run because I thought I could handle more. Then at 70 taps the sap ran better than it had up to that point and I had to boil 2.5 days straight, with my wife handling it5 when I slept and vise versa. That proved to be too many taps.
One thing I did that year when I had no sugarhouse was I set up a 10x10 vendor's tent over the evaporator (on my patio, and on the stack out the back I tilted it back about 30 degrees and braced it using 2 EMT poles and some metal perf. strap. That all worked, and I was hooked. That summer I designed a sugarhouse to be built at my sugarwoods and started dropping several hemlocks and hauled them to a local sawyer to be cut according to my cut list. This finally, after numerous set backs ended in my current 16'x24' sugarhouse. I now wish I had built a 24' x 36' one. I have drawn several sets of plans for a major addition but still have not gotten any further building done (yet).
At first I only planned for a bottler (canner) and a 2x6 evaporator along with some firewood and a couple of chairs. I now have a 3x8 evaporator, a filter press, 2 chest freezers, a microwave, a bottler, a 2x6 gas finisher, an RO, a 10' long wall sink SS unit, a compressor (to run the filter press air powered pump) a rolling tray rack that I bottle to, 2 work benches, a 28 gal draw off tank on wheels, a firewood rack and a heated RO room. I'm extremely crowded to say the least. When you grow, try to plan better than I did.
