Well, there are a few things that you can do to help with the situation. First, there are chests in the bank that you can use to store items. These chests are free of charge, though limited in how much they can hold. Just start using one -- there's no special process to get one. But you can't take them with you.
The other alternative is to buy an ox. These will carry quite a bit, and can be led around.
To get the effect of a campsite, I've combined my ox with a campfire. If you lead the ox out southeast of Hlint, there is some grassland. I've hunted and fished in that area, then made a campfire and cooked my food. My ox stood beside me. The fire only lasts for a few real-life minutes, but it's enough time to feel like you're home (especially if you're a ranger) and to meditate or sing or do whatever you'd do at a campsite. Just remember that your ox is a real animal and can be killed by monsters that pass by, even when you're not logged in, so don't make a dangerous spot your home. To make a campfire, drop some tinder on the ground, then use flint on it. To cook food, use raw food (fish, meat) on the burning campfire.
