We are enjoying our 5th MoHo - 4 Gassers and now a DP.
After reading some horror stories here and elsewhere (more years ago than I wish to reveal), I put the dual spring stabilizer (Steer-Safe) on my then MoHo. It did help in lowering the constant steering wheel motion to keep the rig 'between the lines', but on the next rig I purchased (Our DP) I installed the 'Safe-T-Steer'. I would offer the opinion that the enclosed Safe-T-Steer (while more expensive) is superior if a front tire blowout should happen. The damper of the piston makes it much easier to maintain control and there is less likelyhood of an uncontrolled loss of steering. JMHO
