Slide toppers for 37RLBH

[joelbjr]

Does anyone how to properly measure for a slide topper for the 37RLBH? I to my local Camping World dealer today to get an estimate and they wanted the measurement. I was very surprised when they said they did not have a database of these since the sold the trailer. Guess I should not have been surprised. Would the measurement of the length of the slide out work or is there any type of overlap, or do you use the measurement of the drip rail above the slide out. Any information would be very helpful.

On etrailer website, it is outside flange of box to outside edge of flange or trim.

Sizes fit widths of XX" - XX"s. You want a topper that is 3-4" wider than your widest width of your slide box.

If you need a specific measurement, I could measure mine

I just ordered Dometic Elite slide toppers for my 27.5 RLTS from Makarios RV. They wanted the measurement from the overall width of the flanges.
