I'm wanting to rest my 190 hull on a couple of jack stands and a 2x6 to change out the bunks. What's the likelihood of damaging the hull? Where is the best placement for a 2x6, 6ft long. It would be easier if toward the middle and back but it's more curved there. I could always drive it to the lake but if this won't hurt my hull I'd prefer it. Thanks for any tips.
