Wade, thanks for the input.  I have built a foam/fiberglass boat and built my own boat trailer so would probably not hesitate to make a dual axle mod.  However, one would question if it would be worth the work, as you mentioned just operate within the load and speed limits.  We do not tow the Towlite at high speeds, max 65 mph., higher speeds with a trailer just don't feel good to me, although the Towlite handles very well in all conditions.

We just started to look at the Trailmanor and of course my wife looked at the floor plans and wants the 3326, so I willl get dual axles!  Looking for a good used one here in central midwest.
