RV Description
**Engine Mileage: 125,000 miles (Professionally Swapped, Gently Used Engine with upgraded parts)**
Hey there!
I'm selling my beloved ProMaster van that my wife and I built from the ground up to be our travel home back in 2018. It's been a fantastic companion for countless adventures, handling everything from sweltering hot days to sleeping comfortably in -20°F. Now, it's ready for its next chapter and a new owner to create their own memories in it.
Weve poured a ton of love and care into this van, and that includes making sure the engine is as reliable as the build-out. After a misfire on the original engine, I swapped the entire engine for a gently used one with just 125k miles on it and upgraded the common failure points.
The "Bulletproof" Engine & Maintenance:
Taking advice from a well-known ProMaster mechanic (Kip at Promasters Only in Barberton, OH), I went a step further and "bulletproofed" the engine to prevent all the common failures. This means you can hit the road with complete confidence. Check out his YouTube channel for various ramblings on why this is such a great platform from a mechanics viewpoint - https://www.youtube.com/@promastersonly1419
Upgraded Components: The notorious plastic oil filter housing was swapped for a rock-solid, all-aluminum Dorman unit. I also replaced the plastic thermostat housing and coolant crossover pipe with metal versions from Dorman.
New Valvetrain: All rocker arms and lifters were replaced, eliminating the dreaded "Pentastar tick" and potential for misfires.
Recent Maintenance: Beyond the engine swap, this van is fresh off an oil change with full synthetic, a complete transmission fluid service, and a recent alternator replacement. The tires are also less than a year old with only about 6,000 miles on them.
In total, the upgraded engine parts were about $700 and labor would normally be ~$2,000.
A Thoughtfully Built Home:
The interior is a testament to smart, off-grid design, built for practicality and comfort.
Smart Layout: The swivel table with two benches is perfect for a meal or work and conveniently stows away under the bed.
All-Season Comfort: The van is well-insulated and features a diesel heater with a CO detector for warm, safe nights. On hot days, two Maxxair fans work in tandem to create a cooling "wind vortex."
Self-Contained Water: The water system is designed to be simple and hassle-free, with no cumbersome tanks mounted underneath. This makes winterizing, refilling freshwater, and emptying gray water a breeze. You even have an indoor shower a great storage closet when not in use!
Power for Days: A 225AH battery bank charges via roof-mounted solar panels on sunny days and is topped off by the van's alternator on long drives.
Safe & Simple Cooking: The dual-burner alcohol stove is a safe, non-explosive option, just like those used on sailboats. (Dometic Origo 3000) A 12V upright mini fridge/freezer keeps food cold or prevents it from freezing, no matter the weather (Norcold NR751BB)
Security: A secret kill switch by the drivers seat provides an extra layer of anti-theft protection.
Proven Track Record & Income Potential:
This van isn't just a home; it's a proven asset. It has been a successful rental on Outdoorsy, with many renters having wonderful experiences. This history is proof that all the van's systems are robust and reliable.
