My first portable was the Drake TR33, which was the same size as the 
TR22, but used a single  crystal per channel for both transmit and receive.

There was a similar, but slightly larger rig made by Icom, the IC215. 
That one used the traditional 2 crystals per channel.

Both the Drake and the Icom portables had fabulous receivers.

I never owned one, but Drake made a 10 watt amp and power supply combo 
for the series. The TR22 lay on its back on top of this unit. I have 
only seen one of them in a hamfest flea market years ago, but a friend 
in Alabama ran that setup for years as his only 2 meter FM station.

Drake also made a 25 watt mobile amp.

                     Icom also made a pair of portable SSB rigs for 6 
and 2 meters. These ran 3 watts, and were VFO controlled, but only 
covered the SSB portions of 6 and 2 meters.

I think the models were IC501 and IC502.

When I first got on 6 meter SSB in the late 1970's, I worked several of 
those portables. Many of them were used by people in apartments who 
were only using the built in quarter wave antenna. I knew one guy who 
got his 6 meter WAS that way.
