Sooo... after getting my plates, inspection and VIN assigned, it was time to go camping. We had made reservations at Fort Stevens State Park as a meeting-halfway sort of get together. We were hoping to have the trailer done when we made reservations but figured we could still do it without the trailer. Fortunately, the trailer was done-ish and legal.
The morning of was frantic. I'd spent a lot of time trying to get the trailer wrapped up and we hadn't really given a whole lot of thought as to what we should take, so there was a lot of last minute scrambling. Fortunately we didn't have to get on the road til after noon due to a ferry reservation, so we had a few hours in the morning to get things loaded up. And then, we were off!
Loaded up the trailer felt a bit better than running empty. The axle kit I bought was a 3500lb kit and I had been meaning to get lighter duty springs prior to the first voyage, but it slipped my mind and by the time I realized my mistake it was too close to the trip date. I was able to remove one leaf from each of the spring packs (there were four leafs per pack originally). It made much more of a difference than I was expecting and the trailer rode much better. I'm still going to go lighter on the springs, but for now this works. New springs will go in before the next trip.
Luckily for us, it was raining on day one. We skipped the whole Puget Sound traffic deal by taking the ferry across to Port Townsend from Whidbey Island. It was a bit pricey (over $50) but it did break up the drive for the kiddos. And I didn't have to drive through Seattle.

We moseyed on down to Twanoh State Park on the Hood Canal for the night. It's still very early in the season, but the campground is open year round. There were quite a few empty spots to choose from. Doing it again we would have grabbed one of spots as you first come into the campground. They don't have as many trees over them and are a bit brighter. Since the campground was basically empty, we took a spot close to the restrooms. There are day use parking areas nearby, and judging from the size I would imagine that Twanoh is a zoo in the summertime.

The only issue on day one was finding that the bedding on the top bunk was a bit damp, but there wasn't enough to really pinpoint where the water was coming from. I also found a drop of water in the galley, but again couldn't tell for sure where it came from.
After Twanoh we headed south to Astoria in a torrential downpour. It's been a long time since I've been in rain that hard. The trailer was a champ on the wet and twisty roads and I had to remind myself that it was there a few times when I came into a curve a bit hot. The good thing about all the rain is that it helped narrow down the water leaks. I've got the bunk bed narrowed down to one side of the big window and the galley is leaking through the hurricane hinge. I'll have to do some reading up on the hurricane hinge leaking. I'm pretty sure the water is making it's way around the labyrinth.
Part of this trip has also been experimenting with the transition area from outside of the trailer to inside, and how to do that in inclement weather. The weather, for it's part, cooperated. It dumped solid for four of the five days of our trip. I tried out a larger tarp when we got to our spot in Fort Stevens OR.

For both of the awning setups I ran lines over the roof of the trailer and tied off either to the wheel or one of the stabilizing jacks on the opposite side of the trailer. It worked, but it was cumbersome. Then our friends showed up with an awning mounted to the side of their truck and it was pretty amazing. Much easier than the tarps. Luckily I built some of the roof and wall sections with a roof rack in mind, so I've got a good foundation to attach to. I also learned a lot about the flow of the galley and where I would like things to be for how I use them. It's enough info that can start laying out my first chuck-box.
And, for Tony.Latham, here's a picture in the wilds of Oregon, complete with a shipwreck in the background. Of course, it was also dumping rain and blowing a fresh gale at the time. My wife and kids wisely refused to get out of the truck for the picture.

We had planned on stopping at a friend's property near Shelton for one more night of camping on the way home but we were all pretty much soaked and everything had sand in it. The prospect of another rainy night lost out to slogging out the drive home. Overall, the trailer was awesome. The living space was right for us and, even though the weather was miserable, the trailer gave us enough space to lounge and play some games with the kids. I've got solid feedback from the family as to what we can improve for storage inside and a list of ideas for making the trailer better. Unfortunately, this will be the last trip for several months as I'm just about due to go back to work, but we're already looking at a multi-week trip down the coast and back later this year.
