Axels for 5' wide trailer

I received my full scale profile of a Kenskill from Grant at Lil Bear tears and boy are they great. If anyone is looking for this type of information this is a great service. Anyway, I am now doing research on axles and I thinking of maybe making tear 5 foot wide instead of 4 foot wide. There is much talk about torsion axles on this site and I think that is the way I want to go, so does anyone recommend one vendor over another as far as axles are concerned? Also, does anyone have any strong opinions about making a Kenskill model 5 foot wide as far as the aestetics are concerned?
