See which pools are short, what is on site and what has been sitting too long. Go to **Fleet › Trailers** and open the **Pools** or **Analytics** tab.

## Pools

![Pools: health against the empty target, and Replenish on a pool that is short.](https://storage.googleapis.com/vektor-public-storage/changelog/086c1fee-7fdf-4031-bcb3-8956697dc416.webp "Pools: health against the empty target, and Replenish on a pool that is short.")

The tiles at the top split your pools by health: **Critical Deficit**, **Below Target**, **Balanced at Target** and **Surplus / Donor Pools**. Each row shows how many trailers are assigned, on site and rolling, and has one main action: **Replenish** when the pool is short, **Quick View** otherwise. Click a column header to sort.

## Inside a pool

Open a pool to see its empties against the target, how long trailers have been sitting, detention and per-diem. **On-Site Trailers** filters by **Empty Ready**, **Loaded / Preload**, **In Detention** and **Needs Washout**.

## Trailer Analytics

The **Analytics** tab shows how much of your fleet is working and how much is sitting. **Time Without Manifest** groups idle trailers by age, and **Daily Occupancy Matrix** shows the last 30 days. Click a bar or a pill to filter the table below.

## On the trailers list

- Every trailer without a manifest shows how long it has been idle.
- Flag a trailer for washout, then mark it clean and empty in one click.
- A driver's Custody Timeline shows trailer hitches from up to 8 trucks the driver has driven.
