I call it a virtual fishing trip. TM has to be mounted first. Then sit up in the boat and do what has already been suggested by temp mounting your electronics and holders to plywood and moving them around. What I thought would be the best didn't work very well once I climbed in the boat. I have 9 mounting plates in my rig and use them all at one time or another during the year. Real nice ride you have there. I also mounted my electronics on a riser to make it easier to see and adjust, best thing I ever did. Hi-Tek makes a real nice riser and rod holders.
Creativity is just intelligence fooling around
