For 50 amp service, you could also use larger gauge aluminum, #4 (needs to be terminated properly and conduit size may need to be increased). #6 Al *might* possibly work but check NEC table 310.16. Alum. can be much cheaper than copper.
The conduit at 1 1/2" size appears to be overkill. It looks like according to the NEC, you can get 3 #6 + ground in a 1" conduit (with copper wires). 1" conduit would simplify the work and be cheaper.
As mentioned, perhaps 50 amps is unnecessary and 2p-30 amps will be just fine which would save $$ and make the install much easier. You could still size the conduit for 50 amps in case you decide you want 50 amps in the future.
I highly recommend installing a disconnect switch at the RV receptacle so you aren't plugging the shore power cord in live which will eventually damage the blades on the plug. Should be rated heavy duty or a circuit breaker.
This is an easy method for the average person as long as you have a shop vac. Depending on length and number of bends, a fish tape can work (cheap at Harbor Freight). Pulling wire and gluing the pipe one length at a time is not the normal way of doing it but would work if careful.
To pull the wire, a wire sock works the best and will not let go - these don't cost much. Bending the wire over at the end or taping the pull cord to the wire bundle can be too fat inside the conduit and make it hard to pull. Ordinary liquid dishwashing soap can be used as a lube if needed.

I ran 3 strands of 1-o plus a smaller ground through 100' of 2" for my shop. Tied a string to a plastic grocery bag, shop vac'd it through, then tied a rope to that then finally the wire.
