Short answer is No.
There are several stages in a construction of a motorhome where large item must be glued, supported, lifted high and so forth… Is not about weight but more about size. Two people are the bare minimum. You can still do most of the other jobs yourself and maybe organise few weekends BBQ where your mates can help… ;)
And that reminds me…
Thanks, Paul… Your help was invaluable…
Absolutely Not! As per NHVR Vehicle Standard Guide (VSG5)
Size and dimensions
There are strict limits on the maximum dimension of a heavy vehicle. In particular motorhomes must not exceed the regulation dimensions, including:
• maximum length: 12.5 metres
• width: 2.5 metres
• height: 4.3 metres
• rear overhang: 3.7 metres or 60% of the wheel base, whichever is lesser and including items or equipment mounted on the rear overhang
• combination length (motorhome towing a trailer) – 19.00 metres.
When measuring the dimensions of a vehicle, all equipment that is fitted to the vehicle must be included. For motorhomes common fittings that must be included when measuring dimensions include spare wheels, tow bars, bicycle or generator racks, solar panels, roof racks, bull bars and awnings.
There are other rules, but the ones above are the first one to check when purchasing a vehicle for a conversion. If there is no need for a large carrying capacity, it also pays to remember that your registration (at least in QLD) is based on the number of axles… A three axle coach cost an average of $400-500 dollars more per year compare to the two axles standard bus/coach. Normally the tag axle will give you an extra 4000 kg of carrying capacity..
Remember, there are lots of coach for sale out there longer than 12.5 metres.. We can’t use them..
Even the ‘banana bus’ that really is a bus with a trailer in a permanent composition, it can’t be used either..
No, you don’t.. unless you live in an area where it does often rain..
But not having any protection from the weather, does slow you down (particularly in summer if you live in QLD), and you need to change the way you would normally work to accommodate those weather changes and sometime, it can stop your project all together..
I do recommend some form of tarp or a gazebo (at least big enough for the working table area) as it does make things a lot easier and it can actually save you money in the long run as the project will be completed earlier..
