How to raise fifth wheel alittle higher

I wanna say thanks for all your input, my concern was always the center of gravity. I'm going to consider a longer bumper pull trailer better, do not want to endanger myself, family or others. Thanks again....

My Voltage is already 13'4" high, and I am watching bridge clearances on the back roads. If yours is fairly tall, you might not want to raise the trailer. With that in mind, you might also measure the height at the forward A/C unit to make sure that you're not too high. Personally, I would worry about the stability of towing with a lifted truck, but I worry too much (says my DW).

You may want to measure your overall height before you start raising the toyhauler. You could find your self approaching 14' or even going over that if you raise the toyhauler very much.

Not to mention the very high center of gravity you're going to have. Which could be uncomfortable in some situations. I'd lower the truck.

If you don't want to lower your truck, how about removing the box and putting a little flat bed on it. Would give you plenty of clearance. And, you could put the trailer axels back to lower the center of gravity. Besides, a flat bed will raise the coolness of your truck. :)

Ramp angle gets pretty steep for loading toys also.

There is a product called "Correct Track" that is a bolt on system for aligning trailer axles and will actually raise the trailer about 2 inches. Don't know if that would be enough but it's a start.

Most of the trailers with axles under the springs are already pretty high off the ground. Not sure I would raise one any more.

Lower the truck is the smart move. But since you are unlikely to do that, adding a sub frame is the only option. But that is going to cost you a lot of cash unless you have excellent fabrication skills. That is going to involve supporting the trailer on stands, cutting off all of the axles, springs and spring hangers. Welding a piece of box tubing to the bottom of the frame and then welding new spring hangers. The slightest mistake in fitting or welding is going to make for a very expensive pile of junk sooner or later. Not to mention a very unstable tow due to the high center of gravity.

Lower the back of the truck.
