The time and effort required to turn it into a quad is NOT worth it. If you can't learn how to ride a trike then sell it and buy a quad.

It sounds like your getting the hang of it anyway SOX. With a little time on the machine learning how to ride you will have no problems with it. Quads are easier to ride but 3wheelers are rewarding once you master them.

It will pull a trailer no problems, It might push a bit in the turns, so keep your weight forward and the speeds down when towing. With a trailer hitched low and close to the rear axle the bike should not flip on you, if it wants to flip there is a problem.

When crossing ditches and obsticals get used to how the trike handles, It's better to cross them at right angles, rather than at 45degrees, If you can understand what I'm trying to say.

Once you master a trike you will wonder what all the fuss is about! you may even become hooked....... And end up replying to trike message boards at all hours of the night....... :-)
