Need a recommendation for 7spd rear derailleur

Can anyone recommend a good middle of the road Shimano 7 speed index rear derailleur? It will be for a triple and the chainrings and freewheel need to be swapped for some lower gearing. Probably looking at something similar to a 13-32 rear and 48-38-24 front.
The bike is a 1986 Trek 300 which isn't ideal for touring but should be adequate for the 1 to 2 week trips anticipated.
I'm thinking of a Deore LX or 105 but am not sure on the capacities. Any comments on what has worked for you would be great.

I recommend Shimano Deore front and rear derailleur. You'll want a 42-32-22 MTB crankset. With an 11-34 cassette that should give you a low of 16". Good enough for riding up hills with a full load.

It may be tough to find a decent new 7spd dérailleur however, any 8 speed or 9 speed dérailleur should work, they may be easier to find and cheaper then a 7 speed these days. If your looking specifically at Shimano, check their website, capacities should be there.

Any long cage dérailleur will do. Shifting depends on the shifter, not the dérailleur. The dérailleur is nothing but a spring with a couple of jockeys. If you cannot find a 7 speed indexed shifter, get a friction shifter. You will be surprised with the plasticity and reliability of a friction shifter!

I run a 7sp setup on one of my bikes. It has a triple crankset (48-36-26) and a 12-28 cassette with 105 triple FD and 105-GS (mid cage) RD and 9sp chain. Works great. Shimano says the 105 RD will only handle a 27t cog but I have heard of folks using a 32t cog with no problems.
