The only good thing about LPG is that it can never go more then half of what petrol is worth and that is about it. Petrol has more power, torque, it does not drink as much as gas and they generally more reliable. If your carrying lots of weight get the petrol. Gas is only really good for taxi is or people who drive 6 cylinders.

Good Luck

Go for Omni LPG Van. It is company fitted and very reliable for the purpose you have mentioned.Gas will make it cheapest to run.There is a chinese pump available which can transfer a lpg 14.2 cylinder into the gas tank of the LPG model in less than 3 minutes.Cost about 2000/-

Omni loading van with LPG kit is best option. LPG generally reduce 10 to 15 % of engine power but it will not be problem in your case as loading is less. Go for 40 kg tank. With full tank van will run around 550 km.
