For a newby start used. Dont worry about slides. A well engineered trailer will have good slide out design that can offer years of reliable service. Heck, oir 12 year old fiver with three slides has no leaks and the slide rooms still work like new. The difference on living room is worth it in the end. As a fellow Oregonian the only TT I would consider in your size would be from Northwood Mfg or their sister company Outdoors RV. They build on their own frames, are designed for the rugged PNW. Their only downside is they are heavy, so your going to want a substantial tow vehicle.
