Hi there - welcome to the forums... I have towed with a similar vehicle - a ford explorer with a 6 and a stick. My trailer weighs 2400 lbs and i carry sound music gear and sound equipment. It is not a pretty scene. Your tow vehicle is NOT adequate!
I am in the
same business - a musician and we travel quite a bit..
So here's my 2 cents: A 19 foot trailer is cool for the occasional weekend. That's all! If you are planning on spending weeks at a time with gear, cloths, instruments, CDs press kits, laptop etc.. you need a bigger trailer. 25 to 27 feet. Older ones are MUCH lighter weight. So.... I would consider a bigger tow vehicle. Some of the best buys out there are used vans. Also good for musician's - because you can put chunky stuff in the back of the van - sound equipment, cases etc. And they tow!
