Outriggers easy... A two foot section of PVC septic line filled with spray foam and capped on either side maybe outward maybe 18", aluminum frame..... plate mounts, hinged, fold up and pin when on trailer, pull pin, down, pin lock it in position. Stability x3 or so... Weight carrying up too... maybe 15%....
Two fiberglass bicycle shoop shoops and tear off the flags.... Two 10" sections of hollow round stock plate mounted vertically on outrigger frame on the sides. Shallow water anchors. Shove em down in the mud through the sched 40... 10" will hold the rod well and rods being fiberglass will act similar to shock absorbers for current and such... Out on outrigger frame, distance apart holds position much easier without burning watts...
Damnit. Stop thinking...
