I am leaving in a few days to head to Fairbanks hauling my 33 foot trailer. By April you will be fine.
I disagree with many here...take your boat if you want there is great sailing in Valdez, Homer and Seward. But take a spare for the boat trailer. If you are a competent sailor you wont have a problem.
And while it is true that it CAN snow at any time. At that time of year it doesnt last long (a day) and usually the roads are cleared very quickly...at least in Alaska. This would be low on my list of worries.
The road is good and I am sure it will be no problem for you. Have Fun.
