Built the latest version of the ice cream truck recently. I like the build, especially the giant ice cream bar on the roof, though I do wonder if the ice cream cost $1 or $100 based on the Green Tile 1 x 2 with Groove with 100 Dollar Bill Money Pattern. Logically it is the latter. It must be awesome ice cream for $100!
One comment, avoid the temptation to put the Ice Cream Vendor minifigure on the Dark Bluish Gray Tile 1 x 4 like I did at first immediately behind the serving window so it falls down easily. It goes on the studs two rows behind that window. D’oh!
Comparing it to the pizza van, the ice cream truck is much easier to put the minifigure inside the interior due to easier access with the rear window opening being on a side hinge with a wider opening vs. the up/down hinge system on the pizza van and more crowded interior/inherent space constraints. There is always taking off the roof option though I guess for minifigure placement.
Final thought, they are both loaded with multiple play features and fit quite well within any city layout.
