Took the trailer out for our maiden and shakedown voyage this past weekend. Took lots of notes and discovered a lot of things we'll be doing differently. Trailer was great, heater is very good (but maybe a little noisy, I'll have a look at that). Anyways, got it home an unpacked and promptly dropped off at a friends for the work we had planned. New, wider (68+" to 72") 3500lb axle, bigger 5 bolt hubs, 4 spring sets (previously 3) and larger 13" wheel w/ tires (from 12"). Gave us 5.5" lift with the spring over. Still need to sort out spare tire mounting. Very happy with the results minus a small vibration I am getting at around 80km/h that I need to look at as well.
