What is your Bed rail to the ground height for a FW???

If the dealer said you only need four inches of bed clearance, I would not take their advise on any of the issues involving trailer lift!

IMHO you need at least 6" bed rail/5er clearance. What you need to now is the height of the hitch plate in the back of the truck and the height of the pin plate on trailer when level and unhooked. This will give you some idea as to your clearance. Flipping the axles is the best choice, but in your case may not be enough. From what you post the dealer sounds a little squirrelly. I would talk to some one at a frame shop.

My 2008 Silverado 2500HD measures 57" at the tailgate unloaded and I know that it squats 1.5 inches when hooked up to the fifth wheel. I have air bags to level it out and put it back at 57 inches. I have at least 6-8" of clearance between the rails and the fifth wheel. I wouldn't want any less and it will get pretty close at some gas stations I frequent.

Aswell they said I need only 4" of clearance on bed rails..Just seem like the new fords sat as high as mine.maybe not..I do have a lift on it.So not sure if is possible to do like they said.

They just don't want to do it for you, this doesn't change the the alignment of the axles done correctly!
It would likely take a shop less than two hours, more like one hour with correct lifts and air tools.
It isn't really "flipping" the axles, but placing under the springs rather than over, would require new spring seats on the upper surface of the axle.

Know the new campers and trucks are getting higher..But My wife and I found a FW instead of a tt..Dealer said they can raise the FW with 4" square tubing to accomadate my truck height..
My bed rail to the ground is 63".
Sand piper 345 ret is level is 56".
Any one have this height and have a issue?

Well my 01 Ram is 59" and settles to about 57" loaded at the tailgate, My 5er clears the rails by about 6" and sits close to level. I would agree that 63" sounds a bit tall. Did you look to see if the axles on the 5er were above or below the springs?

I'm guessing your truck has been lifted since my 3500 is only about 57" high at the tailgate. It would be better to return the truck to original height instead of attempting to raise the FW that much.

I don't see many trucks where the bed rail is over 5 feet from the ground. Still the rule of thumb is 6" - 8" clearance. You would have to raise the fifth wheel over a foot. I don't know how that wopuld affect handling but the first step into the unit would be a doozy.
