2 questions - adding LP QD and LP disbribution block question

Ok, I have 2 LP related questions. We are in the process of replacing the underbelly in our Freedom Express 246RKS after some frame repairs. The LP lines are all external to the bottom of the trailer and there is a distribution block near the center of the axles on the entry side. This is a photo of the distribution block which is currently hanging waiting on the delivery of our new belly material for installation.




Here is the block in it's original location along with one of the frame cracks which has not been repaired (photo is for the block in this post)





My first question is... are there any special considerations I need to be aware of in removing and reconnecting each of those LP lines to the distribution block? I'm thinking if I disconnect them all from the block it will make installation of the 1 piece belly coroplast much easier. I can cut a hole for each penetration and snake the flexible hose through it before sealing with the black foam like LCI used when the frame was made. Then once the underbelly is back in place, just reconnect all the lines and check them for leaks. Are these re-connectible lines or are they one shot like some compression fittings?

Second question is, I see an open port on my existing distribution block. I presume that was for the optional slide out grill (which my TT does not have - we just use a Weber Q grill). Is there any reason I cannot add a new line to a LP quick connect port on the bottom of the frame to use with my grill? This would be the perfect time since I'm going to have to deal with the LP lines and the distribution block anyway.

Something like what was done in this photograph (not my photo). And yes I'm aware of the high pressure vs low pressure issue and will mod the grill to work off low pressure (it's the original model Baby Q).

The problem will be that each of the lines at the distribution box will not have a swivel connection. This is a presumption: The LP distribution system is built off production line for each model of RV, then as the unit is being built and when the frame is upside down the LP line system is placed on the unit. The main line is ran towards the front of the unit and the LP tanks, and the other lines are place into holes leading to the LP gas application. Once the frame has been place upright then each appliance is connected with the swivel being at each appliance. I added a line on mine and two (2) friends, dedicated to a Blackstone grill's, such as in the last photo.

I'm not sure I understand what you mean by "will not have a swivel connection". Are you talking about they way these 2 lines seem to have a fairly sharp 90 degree bend just after the distribution block? I can see where a right angle adapter would take stress off that rubber. If I'm removing them to aid in the install, that becomes a "might as well" to fix a potential point of future failure.

Or have I totally missed what your point was?

This is an enlarged section of my original "before repair" photo with the 90 degree bends in the LP hose coming out of the LP block.

I think by "swivel" he is trying to say you will not be able to remove them because the whole thing will be spinning and twisting while you are turning to remove?

I'm thinking of doing this same thing but adding 2 lines. 1 QC and one dedicated to my outdoor kitchen. Im ditching the block and building a manifold. I'll attach swivel ends to the hoses and putting them into the manifold

Yep "Kimber45" that is exactly what I meant. Those are non-swivel fittings swedged onto the LP hoses. IF you attempt to loosen the fitting the hose will rotate with the fitting. You could probably get the fitting loose from the manifold but placing the hose ends back onto the manifold is hard. You would have to rotate the hose/fitting some number of turns, start the fitting back into the manifold and tighten the fitting up.

So if they are IP threads, which they appear to be, they are fixed and not swivel, correct? So this thing probably came as a pre-made block with hoses attached that the factory just plopped into place and then ran the appliance ends through to the other side, etc...
