Well here is the latest news on the subject:
Originally, Camping World and El Toro RV Service both spoke with AMLRV who manufactures Eagle Cap and they both said that the described work can be done and that they would both perform the work as outlined by the manufacturer.
AMLRV will guarantee the repair work for the remainder of their 3-year structural warranty.
OR….They would do the repair at their plant in Yakima, WA but not reimburse me for any travel expenses to get there and back Yakima is 1,100 miles each way).
Today I brought the camper to Camping World.
Upon review, they stated that the suggested repair by AMLRV was not appropriate for the following reasons:
The possibility of piercing the fiberglass while drilling through the floor.
The uncertainty of the proper spreading of the glue.
They did not think it was appropriate that the interior of the camper be compromised in effecting the repair
Camping World is in agreement with my original email that the cap should be completely removed, the area inspected then re-attached to the camper properly.
Let me make this point, this is the first time anyone has actually seen the problem after it being only described to them, including the manufacturer.
I am currently composing a letter to Eagle Cap/AMLRV that I will share with their response.
