Just bought a Platinum 4 horse w/ weekend pkg.
It is a shortbed!
Hauling with a 2005 F250 7.3 Turo charged diesel. 7' by 7'6"
Trailer seems unstable and not nearly as easy to pull as the Hart 3Horse.
Will be hauling 1 or 2 thousand pound horses.
MOst of time 1 horse.
If I buy the pop up hitch extender will it make it more stable?
Do I NEED to purchase another truck? Hope not but will, if I need to I will. Please advise.

See your first post...
Was the 2005 truly a 7.3 liter diesel?

Oops, it was a 2001. Don't know why I said 2005. Thanks for the information. I read it under horse trailer.
