I have a 41 raptor with a 12 foot garage. It would be good for the bikes and I could live in it full time except for the winter here. Winter down south would be fine I'm sure. But loaded I'm about 17k pounds which is too heavy for your 3/4t. BUT a buddy of mine has a slightly smaller 5th wheel that has a 10' garage. Loaded he is about 12-13k pounds which would be fine for your truck. It would work for you but it has less living area then mine. I could full time if I had to but would prefer a bigger trailer. Main thing is look around a lot. Im sure you will find something that will work but with a 3/4t truck you are limiting yourself. Most of these bigger units are 14k empty and it doesn't take mush to add 3 or 5000 pounds.
