Im 6'8" 240lbs and live in the tropics of SEA, where my commute as a farmer is uneven shifting pavement transition to mountain climbing single track in rain run off canyons.

Because I am twice the size of my local friends, is there a cost effective appropriate solution?

I work in agricultural development, so I often have tools or people or 15kg of produce on the back of this jaunt.

I've blown two pairs of shocks. Something that's appropriate for the single track is not appropriate for two up riding long term, and doubling up my shocks causes all the motors equipment to take a beating. I mean, the carb and other items really get thrashed when doubling up my rear suspension.

I have a Honda 150cc, which is the current mountain farmer motorcycle in my country.

I could get a Honda crf family and sacrifice my ability for tools/produce, or a small truck or side car situation I guess.

I am in communities three times a week to teach/project manage, and I'd like to avoid looking like I have money to burn because I'm here to help people, not have my circumstances be drooled over. The foreign currency I saved for this just goes really far here.

Do I really have to own multiple vehicles?

Tldr. Twice the size of typical population where I'm living, having a hard time abusing my motorcycle but also having a hard time accepting I might need more than one vehicle.
