Weight

most are overweight

many are overweight

OK if not downgraded to 7.5.t (Europe)

7.26 t

Width

optimal also for off-road

Ok if track-width outside <= 2 m. Else too wide for Australia but ok for Africa and South-America

Track-width wider than 2.10 m is too wide for small roads, tracks and within villages (Africa, South-America and Australia)

Track-width outside 2 m, overall width 2.10 m

Height

optimal also for off-road

Sometimes marginal because of low hanging power-lines and some tunnels

Often too high (power-lines, tunnels, )

3.15 m

Length

4.5 - 6 m

6.0 - 7 m

> 7 m

5.95 m

Voltage

Truck and camper 12 V

Trucks mostly 12 V but some also 24V, camper 12V or mixed 12V/24V

Truck 24V, camper 12V or mixed 24V/12V

12V

Power

Not enough solar power and house batteries too little

Often there is insufficient solar power installed. Solar power must be dimensioned for bad weather. If usewd ecconomically the battery should last for at least 3 days without sunshine

OK

Solar: 700 Wp. Battery: Lithium 360 Ah = 288 Ah effective.

Storage space

Too litle for long journeys. Too many compromises

OK

OK

Ample storage space!

Insulation

Mostly non-existent

OK

OK

5.5 cm

Security

Too litle space for security relevant stuff (tools, spares, 2. spare wheel)

OK if planning done carefully

OK

OK, lots of tools, spares, and recovery items

Theft security

not enough security

OK, if build with theft security in mind

OK, if build with theft security in mind

Very save. No escape door to driver cab

Comfort

Too little confort because lots of space has to be used as storage area.  Mainly a problem during bad weather areas

OK, but depends on the layout

OK

OK, 1 bed always ready, kitchen always free, 1 seat always free.

Potable water

Usually too little. Daily usage 20 - 25 l for 2 people (includes drinking, body wash, excl. clothes washing). Aothonomy = Nr. of days x 20 l + 4 days emergency x 10 l.

OK. 200 l or more. Authonomy 7 days x 20 l + 4 days emergency x 10 l  = 180 l. 

OK. Too much potable water (up to 1000 l) doesn't make sense, because it is often impossible to get that amount of water or one has to pay for it.

OK. 2 x 100 l in steel-tanks + 20 l in boiler

Fridge/Freezer

Small compressor fridge. Often the fridge has to be shutdown during the night for lack of power

Compressor-fridge. Freezer theoretically possible (depends on the power available)

OK

60 l compressor fridge-box usable as freezer. No explicit freezer

Bed

Camper must be converted. Sleeping across not possible

Conversion mostly necessary. Sleeping across possible for people < 1.9 m. Sleeping longitudinal problematic for a good layout.

Permanent full-size bed across

Conversion from single to  full-zize bed: 1.99 m x 0.75 m resp. 1.99 m x 1.5 m

2. spare-wheel

Weight issue. Easy changable

Weight ok. Weight about 100 kg

Weight not an issue.
Heavey to handle.

1 spare wheel at rear. 1 spare tyre on roof-rack (crane arm)

Recovery utensils / tools / spare-parts

Electric/hydraulic whinch too heavey. Far too little space/weight capacity for security relevant items like jack, hand-whinch, rope, straps, spade, sand-boards, snow-chains, tools, spares

OK.
Heavey!
Requires ample storage space

OK. Very heavey.

Strong hand-whinch, lots of recovery items, tools, spare-parts

Bycicles

Carried outside. Filthy

Mostly carried outside. Filthy

May be carried inside

City-bikes carried inside

Hiking gear (lasting several days)

Space issue

OK

OK

Hiking gear lasting several days.

Seats (in camper)

Typically 2

4 - 6

4 dining. 5 seats

Sleeping berth

Typically 2 (seldom up to 4)

Shower cubical

Uses up too much storage space

Waste of storage space

OK

No enclosed cubical. Shower possible in entry area using a shower curtain or on external stair

Toilet

None or mobile

Mobile or integrated in shower cubical

Integrated in shower cubical

Yes. Mobile in entry/shower area

Cooking

Gas, spiritus (suplies not enough heat) or petrol

Gas, diesel or electric.

Typically gas oder electric

Electric (induction cooking plate, microwave, convection, grill) and diesel stove

Heating

Diesel driven air-heating. Usually too little power to heat trough the night

Hot-air or water floor-heating. Diesel or gas (consumes too much gas)

Hot-air or water floor-heating. Diesel or gas (requires large gas tanks)

Diesel driven water floor- heating with added water/air heat exchange. Connected to motor cooling system

Bridges

OK, about every bridge is good for 3.5 t

A few bridges are critical when not labeled. Own assessment necessary

Often too heavey because bridges are not rated and because the trucks locally used are not as heavey

A few bridges are critical when not labeled. Own assessment necessary
