My Savage Truggy Project!

basically my issue is FLEX...would i want to use a top plate to eliminate it? To give myself more room to place stuff? With the lower TVPs / struts if you will, which merely serve to anchor the bulks to somthing solid, (reducing fore and aft movement), do i need a top plate to reduce sideways flex? Or are the cut down TVPs going to achieve that already? I am all for LESS metal :)
