As a Coachmen Freedom Express owner myself I'd say there's no doubt you're exceeding the 600 lb rating of those E2 spring bars by quite a bit. :E Do the math - your new
FE 236BHS has a factory unloaded weight of 5000 lbs so even if you conservatively estimate your gross trailer weight at just 6000 lbs fully loaded and ready to camp you could easily be running nearly 800 lbs of gross tongue weight at ~ 13%. Such is just one example why (having previously owned a Progress Mfg Equal-i-zer myself) next time around I'd instead select a Blue Ox Sway Pro because if one switches to a trailer in a different weight range one only needs to swap out the spring bars, not the entire system as is the case with the Equal-i-zer and I presume as well the E2 which is manufactured by Fastway which is part of Progress Mfg. If I were in your shoes I'd personally ditch the current E2 and put the proceeds towards a Blue Ox Sway Pro with 1000 lb spring bars. JMO. ;)
