Stockade Puzzle Set

This is the 'Stockade' puzzle, with 2 sets so far... I plan to add more (Stockade 1 & 2). The goal is to fit the pieces from each set inside the box and make sure all of the gaps in the box have pieces behind them. In other words, every gap must be covered up. It may be a little trickier than it seems... Or not, I don't know. You tell me what you think. You might want to print the sets of pieces in different colors, so you do not get confused on which pieces go with which set. The orange set is Stockade 1, and the red set is Stockade 2 in the photos above.

Stockade 1 (Orange) is much harder than Stockade 2 (Red). Stockade 1 is not solvable by BurrTools. It has 88 possible assemblies that will cover all the gaps, but only 1 is solvable. Stockade 2 has 6 possible assemblies, again only 1 is solvable. This puzzle's solution can be confirmed via BurrTools.
