Who makes the lightest 50 amp bunkhouse trailer?

Another way to look at the information given is.

A half ton pickup is usually a decent match for a family with a 5000 lb dry weight TT once it has been loaded for the road.

That would be about a 25 ft TT. These are usually rated for 30 amps.

While two ACs would allow you to hang meat for cold storage, one AC is usually sufficient for a 25 ft TT.

There may be a short 50 amp TT but they certainly are not common.

Good luck
