My inlaws are aging out and they are original owners of a mid 80's ~29' Dolphin with a 20R 4 cylinder engine. RV is in great shape with ~ 80 K miles. The 4 cyl is so under powered that it struggle to go 60mph on level ground and you know the rest on uphill. I'm sure someone has replaced the 4 cyl with a V6, I have seen similar Dolphins that were purchased new with a V6. What is involved in removing the 4 cyl and replacing with a V6. Thanks in advance, Ron
