Hindi naman sila payat ah. Have you and your dad seen one up close in person? Width is actually similar to the Pajero. Matapang naman ang dating. And then I thought length would be a plus since you'd be loading lots of stuff? How much stuff ba talaga?
Pajero Fieldmaster is a good choice. However, do not expect to get good FC with it, especially with the matic variant. Engine is also not very punchy by today's standards.
Want something wide? Hyundai Santa Fe's got a width of 1890mm.

4660mm length means its very manageable too. All seats fold flat, you get great gas mileage and performance exceeding all the above mentioned choices...
