TA Car Rentals, that have an office in ChoengMon Beach have Sukuki 2 door jeeps for 600-700 baht per day depending on the length of rental. This includes Insurance but like most smaller dealers it will not be "comprehensive" and will require you to pay the first 10000 baht in case of damage. In my dealings with them I have found them to be honest, reliable and they have reasonable quality vehicles. If you want complete collision waiver you are best of with one of the major companies like Hertz.
