I have never considered a compost toilet........I will look at that and thanks. As for the gas I need to double check this but I am assuming that it 100% needs to vent outside of the vehicle, and there is no chance of gas engulfing a confined space to cause the unthinkable due to a spark. Many compliance issues will need to be looked at in detail. For e.g. think for QLD rear overhand 60% of wheel base (mine will be in the order of 1,950mm from centre of rear wheel). Gas and plumbing needs to be signed off by appropriate qualified plumber/gas installer. From memory I think the tanks even have to be removable for repairs, changing and the like.Food for thought... Consider a compost toilet (Natures Head, Air Head or similar). It means you don't have to have a black slops tank, and you are not flushing valuable water down the pan... Also, are gas cylinders ok to have within the living area?
Two standard off the shelf roof top tents side by side above the cab would give you those 4 births without having to impact the living area... Now is an interesting time in your build as planning is very important!
Hi Iain, Thanks. The compost toilets seem to be a grand choice?We have a Nature's Head composting toilet, it works great. As for the gas bottles, best stored outside, there are standards for venting that need to be followed. There are regulations for everything, and if you don't comply with them, there is a chance that some bureaucrat in the licencing office will just not approve the registration. You can then try another office, the more regional ones are a lot less strict lol. Your "Engineer" may be a lot stricter, as he has to sign off on each modification, and most take this quite seriously as if there is a problem which causes an accident, they are personally responsible. I've seen a Mog registered that clearly breaks more than one of the "ADR Rules" yet it is registered. It's only if there is an accident will someone start looking.
Looks like that workshop was A1A? Fortunately I have many pro welders in the region (being in the vicinity of shipyards, offshore companies and the like). Unfortunately I don’t have quick access to a certifying QLD Engineer to call upon. Costs could go up dramatically should the Engineer do a 16hour (flight time) round trip journey for an inspection and a beer . I suppose I will just make sure I don’t hide anything that cannot be inspected? Or maybe I will get a weld report carried out for seat bases and major structural portions?
