Bill,
That looks roughly equivalent to my trailer -- if you don't mind the height, it should work (not too much margin on the GVW, though...). Be sure to check the length -- you'll want to make sure your rear wheels are on the level part of the deck or the rear end of the truck may not have enough clearance.
Another thing to think about is how the ramps fold up -- will the rear end of the truck hanging out interfere with the ramps folding up into their travel position? On my trailer, we have to remove the ramps and haul them strapped to the trailer bed or in the back of the hauled vehicle if the truck body extends beyond the end of the trailer -- which can be a distinct pain in the patootie as the ramps are HEAVY and are not designed for quick removal/replacement. That trailer may not be an issue as it's a 20-foot flat with a 4-foot dovetail -- which is a little longer than my trailer. Still, I'd spend the extra $60 for the spring assist ramps -- I wish I had that feature!
If you can, you should try driving your truck up onto one of those trailers to make sure the clearances and angles will work for you. The major disadvantage about deck over trailers is that it can be hard to load long wheelbase vehicles without dragging a muffler or driveshaft on the dovetail edge. Also, be careful about scraping the tailboard edge when you go up the ramps.
Another thing to consider is paying the extra money for the "sealed wire harness." My trailer is not sealed, just wires and it has become a major maintenance hassle.
On the spare tire -- before you spend $140 for their spare, consider heading to the junkyard and getting a stock wheel and tire off a mid '80's F-350. If it's the same axle as on my trailer (which it appears to be), it's the same lug pattern/center hole and tire as was stock on my 4WD '85 F-350.
I'd also consider the dual jacks if you ever think you'll be uncoupling the trailer with a load on it. I got the center stand jack on my trailer and it's not optimal if there is much of a load on the trailer.
The deck on the neck -- I have one and the only time I've ever used it was for hauling hay (stacked right, you can get 600 bales on one of these trailers). It's useless weight I'd rather have available for payload. Instead, I'd go for the pop-up dove tail. My trailer has that and I use that feature a lot.
The king pin coupler is so people with 5th wheel RV hitches don't have to have two hitches. I have a flip ball hitch in my truck and it's really nice and trouble free. You do have to get in the bed to secure the trailer, etc, though.
I hope any of this is useful for you.
Regards,
John
