Look close at Worthington for the money that you spend extra I feel its worth it... Worthington is made in Montoursville Pa. The shop is all local craftsman that have good welding skills , I can not say that about MANY of the trailers I have looked at! A very close second choice is Snowpro trailer made in Maine.
I cant say anything bad out the way my worthington was made, its a production based piece that was built with pride....... Many of the pro line trailer I looked at just didnt have the fit and finish I wanted. DONT buy a trailer that the skin was put on with screws..... My haulmark had holes right threw the skin in 3 years of use ! it was a 2002 model....
the pictures of the red trailer are my old haulmark , look close at the rought holes they are around 20% of the screws that hold the skin on! The real kick in the pants was I contacted Haulmark when the trailer was 18 months old with this problem and they told me its NORMAL ! They did nothing about it...... Never again will I buy any of there crap , or any crap built like theres!
