• Alaska highways have names as well as numbers. Also, watch for small signs with numbers along the roads -- these are "mileposts" that indicate mileage along the road.

• Be prepared. Major repair facilities for RVs are limited to Alaska's big cities -- Anchorage and Fairbanks. Some of the general items you should carry include spare tires, fan belts, a heater hose, electrical fuses, duct tape, extra oil, a tow strap or chain, a small water bucket and flares. Some repairs can be had in such RV-intensive towns as Delta Junction and Tok.

• Interested in travel by ferry? Be aware that reservations for RV space on the ferry system are usually required in advance of travel. If you are willing to travel counter-seasonally (like heading south in June or north in August), then you will find abundant space.

• Most dump stations located outside of the larger cities use a septic tank/drainage field system to dispose of waste. To prevent overloading these systems, please use the dump stations in larger communities that have sewage-treatment facilities. Facilities with dump stations may charge a user fee.

• To see a lot of wildlife, you will need to be up early in the morning or late at night. Watch the mountains for sheep and the valley meadows for moose.
