Joe - base was easy. Found the wood at an art supply store. Went to the hobby shop and picked up woodland scenics sand mat, cut to size, glued and BAM! insta base.
Excellent work. Quite the...RV! ;D
One small thing, no tire tracks behind or around the Stryker, ground looks too "clean" but fine modelin' nonetheless.
Max - base was just a quick job for the show. Sometimes a simple base adds some variation to color on the model itself, it looks better than just sitting on the table . Now if it were a dio setting, then tracks would certanly be in order.
