braking problem

We have a 2022 Forest River Flagstaff Microlite 21FBRS travel trailer. My tow vehicle is a 2012 Chevrolet Silverado 6.2L with the max trailer package.

Hi Larry,

H'mm, I read through all the responses so far, including yours, lets get some more info on your camper and the truck to maybe help better.

1. Is this your camper, https://forestriverinc.com/rvs/travel-trailers/flagstaff-micro-lite/21FBRS/6235

2. It appears the way FR rated this, your GVWR is 5,837# (UVW + CCC) Did I get the GVWR correct? (the truck is OK with that size trailer, just want to make sure we know the camper in question)

3. Have you weighed the camper loaded? If not we can assume you are full GVWR.

3A. What is your added truck bed weight of camping stuff?

4. Is your 6.2 liter Chevy truck a 1/2 ton or 3/4 ton? I'm after this for the braking size. GM often uses the 6.0 gasser in the 2500 back in 2012 time frame, but maybe not always on some high end trim models, just want to confirm.

5. Rather then digging for it, does your truck have a hydra boost braking or vacuum boost braking master cylinder setup?

6. Does your truck have and you are using, the GM integrated trailer brake controller? It appears to be an option per the truck manual. Or are you using an aftermarket controller, and if so, what brand/model?

7. You stated you were using a gain of 2.0 with this new trailer, did you do the brake controller setup test to find the gain required with the manual lever to just be under trailer wheel lockup at approx. 20 - 25 mph? Or was your gain setting of 2.0 from a prior camper and you just left it there? I'm after this to see how the brake controller and the new camper brakes are set.

8. Approx. how many miles have been towed on your new camper since you bought it?

9. Have you towed the camper since this event occurred and did everything work OK or not?

Sorry for all the questions, I'm trying to find a possible link between your setup and the effect of the brake pedal you experienced.

Hope this helps,

John
