It really depends what you’re going to do more of.
If DD aspects are important then I’d say keep what you got and look into modifying with some gearing and/or a tunner. That will have its limitation though. If it’s all about the towing then you need to upsize to 3/4 ton. It’s going have crappy mpg and will likely ride like a covered wagon when unloaded though.
I’ve white knuckled a steering wheels while pulling an oversized load up and down mountains before and it’s definitely no fun.
