Is a tandem axle cargo trailer worth the extra $ over single

OP Here,

Thanks to everyone for your response.

I do not know what the weight requirements will be as we are just getting started. Just as when you buy a truck no one has ever complained about having to much truck! I don't want to have to buy another trailer a year down the road.

Based on feedback here I'll be looking for a tandem axle trailer in the 12 to 14 foot range.

One question as I will be looking at used trailers as well is how can I tell what type of axle is on the trailer?

Thanks again

Dave
