made this the other day after seeing one like this on tv. they sell for $190 and they are called fold and troll. only thing is mine does not fold. here are some pics. i am ging to try this out and i might bend the rodholders back 40 deg. cost $20 including the used post. it does mount into a seat pedistal. i just installed the rod holders. 1 1/4 aluminum tube 60" wide. rod holders are 14". bolts are 3" ss. main bolt is 8" with a stainless sleave that just fits in the whole with a nylock nut. angled this time to 45 deg. i will use 2 1" straps to the cleats to keep it from spinning in the base.
