Bill, if that "toylock" is rated heavy enough for all 6 tires, GO FOR IT !!!
As for getting sun up to me, We've got sun, it's just so cold that the UV rays get frozen out if it before they can "heat anything up"
The pole barn door is slowly "thawing" Today, most of the refrozen ice from the cold snap 2 days ago has melted so we're back to where we were on Tuesday..... COME ON SPRING !!!!!!!!!!!!!!!!!!!!!!!!
