Definitely do it on your own. You will build up your confidence after you are on the road a few days. We took 4 years to plan our Alaska adventure by ourselves and we are loving it. We are currently in Haines, AK. We were RV newbies when we left Massachusetts. Have been in Haines since the middle of June, not leaving till August 1st. Fell in love with it. (if we were in a caravan, would not have been able to stay here.)
Went halibut fishing in Ninilchik, AK. Visioned bears attacking our RV (haven't seen many in AK, more wildlife in the Yukon for sure) and all sorts of bad things. Felt naked without a gun, found we did not need one at all. Rough roads in spots, especially from Haines Jct. to Tok, AK. Just go slow. Visions so beautiful, especially in the Yukon on our way down to Haines, AK that will bring tears to your eyes. Take a deep breath, get yourself a Milepost (your bible while traveling to AK), and save your $$$$, have nice camera, and laptop to store all your pictures and have the time of your life! It has changed ours and we are now starting to think about full-timing in the future!
