Safe ??
Safe to me means staying within the trucks RAWR as its gonna' carry all the load.
This means weigh your trucks front and rear axles. Then subtract that number from your trucks RAWR. The number that is left will be the trucks safe load limit.
Pulling is the other part of towing. Your gonna' be maxed out with the small V6 engine. WE know nothing about the trucks tranny or final drive gear ratio.
Lots of numbers needed when towing/hauling with a small marginal truck.
That size trailer is well suited for a std duty full size 1/2 ton truck with a bigger engine/heavier spring packs.
