If you've been hunting for a trailer that doesn't make everyone feel like they're living in a sardine can, the lacrosse 3510db might just be the winner you're looking for. It's one of those floor plans that makes you wonder why every manufacturer isn't doing things this way. Prime Time Manufacturing really leaned into the "Luxury Lite" philosophy with this one, giving you all the high-end finishes without needing a literal semi-truck to pull it—though you'll still want a beefy pickup, for sure.
Most of the time, when you look at bunkhouse models, you're sacrificing the living area or the master suite to make room for the kids. But with this model, the balance is actually pretty impressive. You get a massive amount of floor space thanks to the triple-slide design, and the "DB" in the name—standing for Double Bunk or Double Bath depending on who you ask—is the real MVP of the whole setup.
The Magic of the Half-Bath
Let's talk about the biggest selling point first, because it's a total game-changer: the second bathroom. If you've ever gone camping with more than three people, you know the morning "bathroom queue" is the fastest way to ruin a vacation. The lacrosse 3510db includes a very convenient half-bath located right off the bunkroom.
What's even better is that this half-bath has its own exterior entry door. This is huge. When the kids are playing outside and someone needs to go, they don't have to track mud, sand, or pine needles through the entire living room to get to the toilet. They can just hop in the side door, do their business, and get back to the campfire. It keeps the main living area much cleaner and gives the adults some peace and quiet in the front of the rig.
A Kitchen That Actually Works
Living in an RV usually means making compromises on how you cook, but this kitchen feels surprisingly residential. You get a massive island in the middle, which is great because it gives you actual counter space to prep a meal while someone else is at the sink or the stove. The solid surface countertops are a nice touch, too—they don't just look fancy; they're way more durable than the laminated stuff you find in entry-level trailers.
Storage is another area where the lacrosse 3510db shines. You've got a floor-to-ceiling pantry that can hold enough snacks to survive a week in the woods with teenagers. The appliances are stainless steel, which gives the whole place a modern, high-end vibe. It doesn't feel like a "camper" kitchen; it feels like a small apartment kitchen. Plus, the oversized refrigerator means fewer trips to the grocery store, which is always a win when you're trying to stay off the grid.
The Ultimate Bunkhouse Setup
The rear bunkhouse in this model isn't just a place to sleep; it's a legitimate second bedroom. Because it sits on its own slide-out, there's plenty of floor space for the kids to hang out, play video games, or just have their own area away from the parents.
It features a flip-up bunk over a jackknife sofa, which is a clever bit of engineering. During the day, you can fold the bunk up and use the sofa for seating. At night, it converts into a comfortable sleeping area. Across from that, you usually have more storage and a place for a TV. It's the perfect setup for families who spend long stretches on the road and need a bit of separation to keep everyone sane.
Living Area and Entertainment
Moving into the center of the trailer, the living area feels incredibly open. The main slide-out houses a huge U-shaped dinette and a plush sofa. You can fit the whole family around that table for a board game or a big pancake breakfast.
The entertainment center is positioned perfectly for viewing from the sofa. A lot of RVs have weird angles where you have to crane your neck to see the TV, but the lacrosse 3510db designers clearly thought about the line of sight. Most units come with a built-in electric fireplace, too. Sure, it looks cool and adds some ambiance, but it's also a functional heater. On those chilly autumn mornings, you can turn that on to take the edge off without burning through your propane.
Built for the Long Haul
It's easy to get distracted by the pretty interior, but what's happening under the hood (so to speak) matters just as much. Prime Time uses what they call "Eternabond Construction" for the walls and floors. Basically, they use aluminum framing and laminated materials that are designed to handle the vibration and stress of highway travel.
The lacrosse 3510db also features a heated and enclosed underbelly. This is a must-have if you're planning on camping in the early spring or late fall when temperatures dip. It keeps your tanks from freezing and helps insulate the floor, so you're not walking on ice-cold linoleum at 6:00 AM. The "Universal Docking Center" is another pro move—it puts all your water hookups, cable connections, and winterization valves in one easy-to-reach, protected spot.
The Outdoor Experience
Let's be real: you don't go camping to sit inside all day. The outdoor features on the lacrosse 3510db are just as thoughtful as the interior. You get a massive power awning with LED lights that creates a huge "front porch" area.
But the real star of the exterior is the outdoor kitchen. It usually comes with a fridge, a sink, and a grill. There's something about cooking bacon outside in the fresh air that just tastes better. It also keeps the heat from the stove out of the trailer during the summer, which helps your AC unit stay ahead of the game.
What You Need to Know Before Buying
Before you go hitching up, there are a few practical things to keep in mind. This is a big trailer. It's nearly 39 feet long and has a dry weight that's usually north of 8,500 pounds. Once you load it up with water, gear, and food, you're looking at a serious load. You're definitely in 3/4-ton truck territory (like an F-250 or 2500 series) if you want to tow it comfortably and safely, especially through hilly terrain.
Also, because of that length, you'll want to double-check campsite sizes before you book. Not every national park spot can accommodate a rig this long. However, if you're mostly staying at RV resorts or larger campgrounds, you won't have any issues.
Final Thoughts
At the end of the day, the lacrosse 3510db is all about comfort and convenience. It takes the stress out of family camping by providing enough space, enough bathrooms, and enough "home" to make the trip enjoyable for everyone. Whether you're a weekend warrior or someone planning a cross-country tour, this floor plan offers a level of livability that's hard to beat. It's a solid investment for anyone who wants to bring the comforts of home along for the ride while they explore the great outdoors.
