Can someone measure the lowest point of your trailer to the ground? I am doing a major modification to my trailer and I forgot to measure the factory low point. I will share my mod after its complete. I am modding our trailer to carry a trailer mover behind the boat, so we can launch our boat ourselves when we travel with the RV. It involves hydraulics and sliding axels.
 
Are you still on the MFI trailer? I have the 21’ but I am sure they are nearly identical as far as the low point is concerned.
 
After leveling the trailer, from the ground to the bottom of:
Forward crossmember: 10.25”
Second crossmember: 10”
Third crossmember: 10.25”
Aft crossmember: 9”
Bottom of protruding u-bolts at axle plate: 7.75” (technically lowest point except for wheels and jack)
Bottom of axles: 11” (topped with 53 gallons on board)
 
@Seadeals Thank you very much! Huge help!
