Yea, I usually normally do not use the TX tray because I take several to the field anyway. Ideally the two small drawers could be replaced by a single large drawer for the TX. If you do not cart as much as me to the field, the TX will also fit in the lower compartment (it is big).
Overall, it is a nice size, fits in most trunks, easy to carry up the basement stairs and will not topple or slide around in the trunk.
