Well lets hear them pro's and cons. I need to buy a new one in the next few months for my boat build, last one was only 3 weeks old when it was hit by an SUV. It was a galv. steel magic-tilt. I can buy a new MT steel trailer for about $900, for about $600 more I can get an aluminum magic-tilt. I know the obvious corrosion resistance issue aluminum is well suited for, but I remember hearing something about electrolysis between the galv. steel tongue and the aluminum trailer frame. Looking for any real insite. Also worried about theft as aluminum is pricey stuff these days.
