2021 Gulf Stream Envision 21QBS One Owner, 11,690 Miles, Turn-Key Setup

Status: Clean Title in Hand | One Owner | Non-Smoking | Pet-Free


OVERVIEW
If you are looking for a completely dialed-in, road-proven travel trailer that is ready to camp this weekend, this is it. We purchased this 2021 Envision brand new and have meticulously logged approximately 11,690 miles across incredible trips to Maine and the Dakotas, along with many trips in Wisconsin and the U.P., with zero mechanical issues.

Unlike trailers that sit idle or lack maintenance, this rig has been upgraded proactively for safety, durability, and true peace of mind on the highway. It is an exceptionally clean, well-proportioned layout that feels incredibly spacious thanks to a deep slide-out and a true, solid-door rear bathroom.

THE "RELIABILITY TRIFECTA" ($1,500+ IN PROACTIVE MAINTENANCE)
- Premium Goodyear Endurance Tires (2024): Complete set of 5 upgraded highway tires (including matching spare) to replace the cheap factory originals. Maximum safety and stability at interstate speeds.
- Proactive Roof Protection: All major roof seams have been permanently sealed with high-grade EternaBond tape. This is a massive upgrade over standard factory caulk to ensure a 100% watertight cabin for years to come.
- Wheel Bearing Service (2024): Wheel bearings were completely serviced and repacked.
- Upgraded 100 Ah AGM Battery (2022): Replaced the weak factory-standard battery with a premium, high-capacity 100 Amp-Hour AGM battery. This heavy-duty upgrade provides massive reserve power for off-grid camping and requires zero maintenance (no checking water levels or dealing with toxic corrosion), giving you maximum reliability and peace of mind on the road.

TRUE "TURN-KEY" CAMPING PACKAGE INCLUDED
Why is everything included? We have decided to close our camping chapter to focus on other family goals, meaning we no longer have a need for our trailering gear. We would rather see these high-quality accessories go to the next owner to get them off to a perfect start, instead of letting them sit in our garage.

This is a massive bonus for a first-time buyer looking to skip an expensive $700+ run to the supply store. The following gear is fully included in the sale price (see driveway layout photo):
- Wireless Digital Rear Camera & Tow-Vehicle Monitor: A complete plug-and-play system that works flawlessly. It gives you full-time observation down the highway and eases the stress when backing into tight campsites.
- Fastway e2 Weight Distribution & Sway Control Hitch: Premium trunnion-style, dialed-in and ready to couple.
- Heavy-duty leveling blocks and wheel chocks.
- Electrical surge protector, heavy-duty electrical adapters (dogbones), and sewage hose kits.

SMART MECHANICAL & TECH FEATURES (BUILT FOR FLEXIBILITY)
- Upgraded Digital Tank Monitors (Mopeka Bluetooth System): Skip the notoriously unreliable factory tank gauges. This trailer includes a premium, aftermarket Mopeka wireless sensor network (see app screenshot in photos). It syncs directly via Bluetooth to your smartphone to give you 100% accurate, live percentages for your Fresh Water, Grey Water, and both Propane (LP) tanks. Extremely user-friendly for peace-of-mind monitoring.
- Versatile 2-Way Refrigerator (110V/Propane): Unlike newer 12V-only models that can rapidly drain your house battery in under 24 hours, this traditional 2-way fridge gives you total flexibility. You can plug it in at home to get it ice-cold before your trip, and it will run efficiently on propane while youre towing down the highway or a couple nights of boondockingno expensive solar upgrades required.
- Three burner stove with built-in ovengreat for a batch of cookies, cinnamon rolls, pizzas, lasagna, etc. Microwave oven also included for to maximize flexibility and convenience.
- Reliable 6-Gallon Gas/Electric DSI Water Heater: A highly dependable, easy-to-service system with clean, easily accessible bypass valves. (Please note: later model years switched to tankless, but this 2021 features the preferred, reliable standard tank system).
- Kitchen Sink Covers: Molded matching covers to maximize your food prep workspace.
- Bring Your Own Comfort Mattress: The trailer comes with the original factory mattress. Because factory RV mattresses are notoriously basic and sleep preferences are completely personal, we left it as-is so you can choose the exact residential mattress topper or upgrade that fits your style.

LAYOUT & SPECIFICATIONS (FLOOR PLAN INCLUDED IN PHOTOS)
- Smart 21-Foot Design: Features a deep slide-out that opens up the main living space significantly, making it feel like a much larger rig.
- True Private Bath: Features a solid-door rear bathroom layoutnot a cramped corner wet bath or a flimsy curtain.

CONDITION & TRANSACTION DETAILS
The interior is immaculate, the command center and all electronic tank monitors function perfectly, and the slide-out mechanism and power awning are fully functional. Never any pets or smoking in this trailer.

If you have a properly rated truck, you can literally hook this up and pull it straight to a campground tonight. Serious inquiries only, please. Feel free to message via the RVTrader contact form / email to coordinate a viewing or ask any specific questions!
