Alaska has one of the highest gas prices in the US. I think you have allowed a good amount. I looked on gas buddy and at the moment the cheapest price is $2.99. Thinking it will go up in the summer. You also seem to be in the ball park about MPG.

I've only met one person (a woman in Ohio) that was really negative about towing a trailer behind a motorcycle, and I suppose she had a good reason to feel that way.
She and her husband were probably in their early 60's and they had an Ultra and a trailer (not sure of the brand or type).
According to her, they were riding on a two-lane highway when one of the trailer tires blew out and he lost control of the bike and dumped it.

After the crash, she noticed that the trailer had somehow "jack-knifed" and was laying very close to her head and she swore that they'd never have or pull another trailer.

Trailer tires are critical components, as are bearings, when being towed by a motorcycle and a failure may cause anyone to lose control of their motorcycle.
Tires need to be less than 6 years old and on long, freeway trips the pressure needs to be checked daily, before getting on the road.
"Buddy Bearings" are a must and I carry a mini-grease gun and give each one a couple of squirts after a days ride or when ever they need it.

 

My trailer came with bias ply tires and had one break a bead in the Badlands. Replaced them with radials. I feel it really improved the way the trailer feels behind the bike. I usually pull the hubs and repack the bearings before each season.

 

The only thing I can say about the issue is last year I pulled into a gas station in Iowa to get gas and just as I turned off the bike the guy next to me said "do you know you have a flat tire on your trailer"? I didn't know it and I don't know how long I had it. I drove it to a tire place (about 5 miles) and they plugged it for me for free. I love Iowa!

 

My parents have towed a trailer all over the country and I finally joined the ranks of towing one this year. I am looking forward to having my bags and tour pack "empty" on a trip. Plus there won't be any lip between the wife and I while packing when she wants to bring 6 pairs of shoes and half of our bathroom for a weekend trip.

Most of the group that we ride with have trailers and they all love it.
Only issue I am aware of is my dad once had the ball come loose while riding, they didn't go down but it was one hell of a ride trying to stop it from highway speeds.

 

Do you guys use chains?

 

I am still laughing. I remember when I traveled for a week with a small duffel bag. Now I have a trailer and it is full.

 

I use chains but if the trailer came off the ball somehow (I use a lock too) it would be very dangerous and hard to stop.
