We pulled our 36' Mobile Suites to Alaska in 2013 with our '08 GMC dually. We had no problems on the trip, however some of the roads are fairly rough. Pay attention to those little orange flags that indicate frost heaves. We stayed several days in some spots so were glad we had a larger space. The mosquitoes were pretty bad, mostly in parts of Canada so we didn't spend a lot of time outside. We didn't have too much of a problem with them in Alaska. The weather can be cold and rainy, however we were quite fortunate that summer. I remember being in Anchorage and hearing a DJ on the radio comment on the fact that they had broken a record with 14 consecutive days of 70 degrees or more and no rain. I don't think this is the norm. Have a great time, Alaska is such a special place!
