94 Toyota Truck questions re maintenance, lifting, coolant change....

I own a 1994 Toyota Truck, 2wd, std cab, 4 cylinder, 5 speed, AC, all stock cond. It has 70,000 miles on it and I'm the original owner.

I pull a 5x8 utility trailer with a 2000lb load and 100lb tongue weight for the last 5 years.

The tail end of the truck sits lower then the front.

1. How can I raise either the entire truck or just the back end of it safely and inexpensively? What is the best way to do this?

2. I also need to change my radiator coolant. Is this easy to do? Do you know where I can find step by step instructions on how to do this?

3. Also interested in getting a rear bumper with a 2 inch reciever for towing. Who makes the best bumper with the highest ground clearance?

4. Can you recommend the best owners/repair manual for this truck?

5. I have only done oil changes on the truck. What should my priorities be on maintenance? What needs to be done? I've lost my owners manual.

Any websites with info would be helpful.

Thanks

well, if im not mistaken, you can put (i think) 1 inch lift shackles on it... i think the 2wd pickups have torrision bars also, so you could raise those after you lift the rear... if its too high for your taste.
