the 27hfs has a 900 tongue weight so I would think 750 would be to light...just my uneducated opinion... seems the dealers either don't care or don't care to know..... I've installed firestone air bags to help out even though they say not to use the air bags with the hitch, I've read that people do and get better ride and handling...I'll let you know nov 8th..lol...I would think with the 1800gw like me( 1500# for the two Harleys) you have to get the nose down a little to equal the weight out on the trailer axles or need some front ballast which is my next step..I,ll let you know if I figure it out...please do the same if you do.....
