I have a 19' nitro 901 cdx and would like to be able to park it on my driveway. Problem is my driveway has a decent slope away from the house and the boat has to be backed in due to the driveway being too short. Also, the garage is too shallow to park the boat in there. With wheel chocks and a floor anchor with chain/cable attached to the trailer for extra security I'm not worried about the boat moving when taken off the truck. My question is, what are options if any for the trailer tongue? With the downward slope I'm afraid there will be too much pressure on the trailer jack wheel. I've thought about wood block a cinder block or something like that but I'm still afraid of it possibly tipping over with the weight. Anyone dealt with this situation? Or is this something I should stay away from? Thanks in advance for the help.
