Deep Dive: LMTV Bliss Mobil Stats

We often get technical questions regarding our LMTV Bliss Mobil expedition RV build stats – it’s unusual and one-of-a-kind. I’m a geek so I appreciate the curiosity and compiled this list of everything I could think of. Let me know if there’s something missing or incorrect.

Truck

We chose a surplus U.S. Army standard cargo truck as our base for the vehicle. Specifically, ours is a 2006 LMTV (Light Medium Tactical Vehicle) model M1078A1R. Couch Offroad Engineering prepared our truck for us. Acela Trucks also does great work on LMTV/FMTV trucks.

  • Manufactured in USA by Stewart & Stevenson
  • Caterpillar (CAT) C7, 7.2-liter, 6-cylinder inline water-cooled turbo diesel producing 330hp (boosted from stock)
  • Allison 7-speed automatic transmission, 6.14 gears
  • Full-time 4×4
  • CTIS (Central Tire Inflation System)
  • Cruise-control (after market)
  • Tires: Michelin 395 / 85R20 XZL’s which are 46” tall and 15” wide
  • Wheels: Hutchison beadlock
  • Tire/wheel weight: ~ 330 lbs
  • Length: 25’ (including motorcycle carrier), 40’ with trailer (see below)
  • Weight: 26,000 lbs – LMTV with Bliss Mobil box
  • Height: 12’ 4” – including Bliss Mobil box
  • Fuel capacity: 112 gals
  • Fuel efficiency: 6 mi/gal –  highway
  • Range: 672 miles – highway
  • Top speed: 70 mph
  • Comfortable cruising speed: 55-60 mph
  • Top speed on 6% grade: 40 mph

One comment we often hear is “That thing could go anywhere!” It certainly looks like it but it’s not completely true (Hello narrow ATV trail!).

  • Water fording depth: 50” – I’d never take ours through 50” unless I’m willing to let the storage boxes get full of water – I’d also worry about water seeping in around the Bliss Mobil door.
  • Additional rear spring added for better capacity and stability

House (Bliss Mobil)

Our living quarters is from Bliss Mobil in Breda, the Netherlands. The 15’ model is designed to go “off grid” for up to 30 days.

  • Fresh water: 460L (121 gal)
  • Grey water: 220L (58 gal)
  • Black water: 110L (29 gal)
  • Water recycler / maker – can produce 70-100 liters clean water per hour from grey water or any outdoor water source
  • 4 solar panels with combined capacity of 0.96 Kw
  • 2 parallel lithium-ion battery banks with combined capacity of 22kW/800 Ah
  • 40-liter capacity freezer
  • 83-liter capacity fridge
  • 6100 BTU air conditioning/heating
  • Diesel air heater

Trailer

When we moved from our home in Oakland, CA, we were not sure what we would need so added a trailer as our “garage”. It turns out we really don’t actually need most of what’s in the trailer and will be working to eliminate it by end of 2018.

We chose a surplus U.S. Army M1102 Light Tactical Trailer. This trailer was designed to be pulled by a Humvee (HMMWV M1097/M1114 series) but looks great behind the LMTV. The M1082 LMTV trailer is way too heavy duty and tall for our purposes.

  • Tongue extended to clear the rear motorcycle rack overhang
  • Custom storage enclosure and roof-top rack by Access Manufacturing – Expedition Supply provides sales and support

Cost

Another common question is about cost. The short answer is, it’s about as much as a small house. At the risk of mis-quoting the vendors, I recommend getting standard pricing from Bliss Mobil and Acela. Or DM me.

  1. The Two if Overland folks reported that they averaged 8.1 mpg in their 6×6 LMTV which is bigger and heavier than your vehicle; any thoughts on why your mpg is 75% of theirs?

    How comfortable is it driving long distances in your vehicle? My reason for asking is that I am still working and will be for a few more years; until then I will not be in a position to travel for extended periods of time; I live in MA and would like to explore far from my home and do not want to spend more time traveling to and from a distant state – say Montana – than I actually spend exploring.

    1. I’ve only taken one good measurement so far and it was mixed on/off highway. I have two tanks and keep forgetting to make recordings on how much I’m filling each tank and switching between tanks before recording miles. That’s all to say, I’ll keep measuring and report any changes.

    2. Forgot to answer the long distance question – I’m comfortable 5-6 hours and then I fatigue. It might be more me than the truck, though…

  2. Darrel,

    One other comment; I too beat cancer; I had diffuse large B cell lymphoma; my last chemo was 2/28/11; stopped all meds about two weeks later and have not looked back.

  3. Hello there wanderers, I saw your rig in Bozeman this afternoon from my hotel room. I had to go see it. Unreal! Congrats to you on your cancer fight and doing what most people would never do. I’m a car and truck geek and this thing blew my mind. I will follow you on your journey. Good luck!
