I decided on a chariot trailer (cougar) for two riders. We looked at a few other brand (copilot, instep,burley)and wasn't impressed with burley(higher quality one) at all. My son just sank in and was pretty much slipping off the seat even having it adjusted by me and the rep at R.E.I. Wow the chariot sure gets expensive this trailer I didn't realize you had to pay for the cycling kit(arm). Sheesh they can at least throw that in after the $500 your paying for the thing lol! So we decided to go home and do some surfing on the web and wahla we found it for $519.24 no tax, $10 shipping on the cycling kit. I bought it from www.livingincomfort.com My hubby found a promo code: take30 (which was $30 off of $500 or more purchase) cool huh! At the store it would have turned out to be about $598.00 and some change. We saved about $73.00 and some change! So if anyone else is thinking of ordering this to me a was a great deal! Thanks everyone for the input early on with all my crazy trailer questions!!!!!!!!!!!
