I'm looking at upgrading trailers possibly and wondering if anyone else has any experience with either a Haulmark Grizzly model or United UXGN. Both that I'm comparing are 32ftx8.5ft Gooseneck trailers with tandem 7k axles. The Haulmark is $2500 less then United. Also the trailer I'm getting rid of is a 2002 United 25X7 enclosed, full laun liner, oil rack, toolbox rack, 8ft fold up bench, furnace with ducting, RV 110v to 12v converter charger, 12 flourescant lights, 12v regular lights, built in LP tank and battery compartment, aluminum wheels, LED marker and backup lights. Tires were replaced last year along with alignment always kept inside. I would say its in good condition probably great considering that its 11yrs old. What do you think its worth. Thanks for any help.
