Wow 340 miles! That's a lot further than I thought - I need to try it at 56mph, when I do I'll post up.
Yeah, you're right, with the extra load, will reduce that. When we've got all the kit on:
2 weeks clothing and miscellaneous stuff.
We're also going to be running on all terrain tyres and steel wheels.
I like your thinking, the LPG tank is good for 280miles, mainly cruising at 70mph, so it would be a useful top up.
Not knowing how long this will last us over the 2 weeks, we would still need the jerry can back up, but that's a useful tip :-)
The switch over is pretty much seamless and smooth with no hiccups.
There's a switch on the dash very much like this:
The vehicle starts up automatically on petrol, when the engine reaches the right temperature, it will automatically switch over to LPG.
If you want to run on petrol, you just press the petrol button, when you want to switch back to LPG, just press the LPG button.
When the LPG runs low, it will emit an alarm and flash, you have to manually switch it back to petrol.
If you want to, you can start the engine on LPG but only should do this if you have to.
Running on LPG is pretty good, it's a tiny bit down on power compared to running on petrol.
To fill our LPG tank it costs about $90 and usually lasts 5 days of commuting 32 miles a day, depending on how fast you travel.
Filling up with petrol costs around $166 and wouldn't last the 5 days.
I was thinking of running with the LPG to get to Denmark, but I suppose we could take the hit and use the petrol only.
We take the ferry from the northern tip of Denmark to Iceland, but we can either drive to Denmark or take the ferry from the UK to Denmark.
I'm thinking that we could take the ferry to Denmark then take the kids to the Danish LegoLand on the way.
BTW this is the trip brochure:
