Payload on used truck?? -- can't weigh beforehand

Here's the thing....

It's impossible to always be where the weather is nice. I know. I tried.

So you end up with layers of clothes for every season and occasion. Toss in a few extra tools and toys for a two year haul, and you end up with a very large camper stuffed to the max. A very heavy load indeed.

Quite frankly, if a dually isn't in the budget, ought you be going at all?
