Just got back from a 3 day camping trip in the mountains, near idyllwild, Ca. I have a 2004 electra glide ultra classic, with very few mods, true duals, screaming eagle mufflers (pre 06), pcIII and air cleaner, I was realy disappointed in the power, I was pulling a cycle mate trailer. My question is for those that do pull a trailer, what mods have you made. This is my first Harley in 46 years of riding.
