AT Overland's latest Aterra ASI camper establishes a new benchmark for adaptability. Combining ultralight design with cutting-edge modularity, this slide-in camper is offered as a build-it-yourself kit and a completely assembled version. It appeals to all types of adventurers—from dedicated do-it-yourselvers to those looking for top-of-the-line amenities right out of the factory.
AT Overland has built a solid reputation through the creation of tough, practical, and inventive campers tailored explicitly for adventurers. Their most recent offering, the Aterra Slide-In (ASI), upholds this tradition—offering adjustable flexibility, robust lightness, and substantial off-roading capabilities within the crowded slide-in camper sector.
The ASI, as part of AT Overland's latest addition to their Aterra line, marks a notable advancement in the realm of slide-in campers. This completely closed, solid-side model is crafted using cutting-edge honeycomb composite technology. Designed with an emphasis on flexibility, user-friendliness, and robustness under tough outdoor environments, this unit caters perfectly to those seeking top performance among truck campers.
Lightweight & Durable Construction
The ASI's appeal starts with its cutting-edge and lightweight design. This camper features an advanced honeycomb composite structure strengthened by polygonal geometry, and both the interior and exterior surfaces are covered with UV-resistant hybrid polyurea and polyurethane coatings.
This building method offers exceptional resilience to severe weather and tough landscapes, all while considerably decreasing the camper’s weight when contrasted with conventional constructions.
For individuals aiming to construct a robust, hard-sided camper compatible with a mid-sized or half-ton pickup truck, the ready-to-assemble shell has a remarkably lightweight starting point of only 757 pounds. This makes it highly appealing for people who have restricted cargo capacity. The better-equipped Standard version also remains relatively light at merely 817 pounds, providing versatility for long-duration, off-road expeditions.
I got a chance to see a completely outfitted ASI camper at AT Overland’s base in Prescott, Arizona. This setup was installed on a truck with a 6.5-foot bed. Toyota Tundra .
And, equipped with optional amenities such as a forced air heater, air conditioner, water system, shower, fridge/freezer With features including a sink, toilet, and storage compartments, it had a manageable weight of 1,157 pounds. The vehicle’s aerodynamic shape and robust structural design minimize stress on your truck, making it suitable for both highway cruising and rugged off-road paths.
Do-It-Yourself Shell Campers vs. Fully Fitted RVs
One of the most attractive aspects of the Aterra Slide-In is its capability to effortlessly serve two different groups: enthusiastic do-it-yourself enthusiasts and individuals seeking a fully prepared, ready-to-use option.
Mario Donovan, the CEO of AT Overland, promptly highlighted that the fully loaded Standard model, which costs $31,995, provides an undeniable better value proposition. By investing approximately $2,000 extra compared to a base model, customers get a vehicle outfitted from the factory with premium features such as a Redarc Manager 30 power management system, a Lion Energy 105Ah lithium battery, and 185 watts of rooftop-installed Sol-Go solar panels.
Given the expense and difficulty involved in obtaining and setting up these high-end parts individually, the Standard model becomes a compelling option for the majority of purchasers.
Nevertheless, for those who prefer building from scratch, AT Overland offers a DIY shell package—complete with professional support—which stands out as an encouraging choice. According to Donovan, "Customers have the option to contact us and select from multiple prefabricated modules designed for easy installation onto their campers. This allows them to begin with a simple setup and expand it over time based on either their financial situation or changing requirements."
Inspired Interior Design & Top-Quality Amenities
Within the Standard model, AT Overland’s careful design approach shines through. The expansive cabover bed spans 74 inches by 80 inches and features a robust 3-inch-thick mattress topped with a resilient Sunbrella fabric cover. To avoid hindering your interior area, the bed employs a distinctive folding mechanism. Additionally, should you prefer, you can keep the bed stored away and opt for sleeping lengthwise in a more compact bed instead.
Adjustable LED indoor lighting paired with an inviting outdoor entryway lamp provides functional brightness while maintaining atmosphere.
The inside focuses on maximizing spatial efficiency. A front power cabinet (which can be extended to hold up to two Dakota Lithium 320Ah batteries) offers not only storage for electronic devices but also serves as comfortable seating.
Wall-mounted folding tables at countertop level provide crucial spaces for meal preparation and eating without cluttering the space inside. Superior dual-paned windows ensure excellent insulation, enhanced by reflective privacy shades and bug screens.
Each ASI camper includes a standard set of safety features such as a fire extinguisher, carbon monoxide and smoke detectors, a My Medic first-aid kit, and a durable Fenix flashlight, highlighting AT Overland’s comprehensive strategy.
Extensive Options for Personalization
The AT Aterra Slide-In camper really stands out due to its vast customization options. It’s built specifically to grow with the owner's expeditions, as AT Overland provides an assortment of useful enhancements tailored for various travel preferences.
Donovan stated, “We designed the Aterra with adventurers in mind—those seeking a lightweight, sturdy, and flexible RV that can be effortlessly customized and enhanced.”
For those who love outdoor cooking, modular kitchen designs feature robust bamboo surfaces, plenty of storage compartments, spaces designed specifically for high-end refrigerators such as the National Luna 50L, and versatile cooktops meant for both indoor and outdoor use. To handle water efficiently when not connected to utilities, these kitchens offer an option for sleek stainless-steel sinks equipped with electric taps, complemented by a practical 12-gallon fresh-water reservoir.
External shower choices consist of the Joolca hot-water setup and readily set-up shower enclosures. This guarantees ease and comfort without complicated setups.
The climate control settings are also fully adjustable. For chilly trips, travelers have the option of using robust systems such as the Truma Varioheat forced-air heater. When facing warmer conditions, they might opt for the rooftop-installed Nomadic X2 air conditioning unit instead.
Campers who prioritize storage space will find value in the modular compartments capable of holding up to 15 Step 22 Stingray Flat Boxes, complemented by additional MOLLE panels for enhanced equipment organization.
Flexible toilet choices like the environmentally friendly Trojolo composting toilet or Wrappon sealed toilet enhance both space utilization and comfort during prolonged outdoor excursions. For those who work remotely, AT Overland provides a conventional rooftop direct current port designed specifically for mounting a Starlink Mini satellite internet system, guaranteeing consistent online access even when far from urban centers.
The top-of-the-line version I visited at AT Overland’s premises highlighted numerous optional enhancements such as forced-air heating, an advanced water management system, a National Luna refrigerator/freezer, a composting toilet, ample storage spaces, and enhanced seating options. Priced at approximately $45,000, this unit vividly illustrated the adaptability and high-quality features of the ASI, which can be customized according to personal expedition goals.
Designed for Real Off-Road Expeditions
AT Overland’s steadfast dedication to off-road capability is ingrained in the Aterra Slide-In’s construction. This camper includes an innovative self-adjusting, bolt-on mounting system. Unlike traditional campers that rely on complicated turnbuckles or belts, the ASI’s engineering makes attaching and detaching effortless yet ensures a remarkably sturdy link, perfectly adapted for demanding off-road excursions.
The lightweight design, sturdy composite build, and easy installation greatly improve the car’s maneuverability, steadiness, and safety, especially during challenging terrains, steep ascents, or tight paths.
Overlooked potentially is the polygon-shaped design, which offers not just an aerodynamic profile but also enhances clearance at the upper corners of the camper. These areas are typically prone to damage from branches hanging low overhead.
The flexible design concept of the ASI allows it to adjust seamlessly to changing living patterns, catering to expanding households, fluctuating travel preferences, or ongoing personalization projects. With factory-supported assistance, independent travelers can rely on professional advice at every step, ensuring the camper remains a wise choice for sustained use over time.
