Trailer size?

[moreyes]

My next rig will be Pro V 1800 IFS, I am going to get a Eagle trailer, is a single axle big enough or should I go dual axle? I was thinking by the time you get a kicker,4 batteries, full windshield, and whatever else, that adds up in weight. I have seen 1900 on dual axles. I generaly dont push it around by hand.
