Alaska roads street the border require 40-45 mph in some places due to frost heave, and also on the road to Glen Allen. Otherwise you're dusty but clear through to Palmer. Done beautiful spots along the roadside and up on the plateau but watch out for evening fog.
Wasilla offers water at $5/167 gal. But don't use a filter out anything else that will slow the pump down or it'll stop. The laundromat there is pricey, the Carr's store is open 24 hrs, and the visitor center/ museum is very helpful. Make sure you have plenty of data roaming unless you have ATT or a local service; wifi is hard to come by. Lowe's and Target offer it, among the usual coffee shops, library, etc. Downloading offline maps is a big help to reduce your usage. DM if anyone has specific questions. Hope this helps.
