Radio for '87 Dolphin

On the Crutchfield website---"What fits my car"

If you have the stock Toyota radio in there, most any standard radio will fit. Try an independent car audio shop. They can look at the vehicle in person and give you some real world suggestions.

Why not try secretaudio.com They can make reproduction radios and hidden radios. Your wallet is the limit.

You can install a new stereo in the glove box. I ended up doing this as my clipper had only an AM radio in it - I liked the retro look of the cab, but wanted to have a CD/AM/FM stereo with auxiliary plug. Now, if someone looks in, there's just the AM radio. But behind the door to the glove box is the actual working stereo.

Best thing, no cutting into the dash was necessary. Having a stereo with a remote comes in handy if you can't reach the glove box from the driver seat while strapped in.

Crutchfield can help you find an appropriate radio if anybody can. If you can't find the RV itself in their listings (which may well be), if it's dash mounted it's probably the same as the Toyota pickups for that year, and my guess would be be a DIN or double-DIN mount...which is about as common as they come. (If it is some other configuration, your choices without modifying or adapting the dashboard opening are going to be quite limited.)
