I had my first heart attack about 10 years ago. I had a lot of heart damage as I actually ruptured my heart. My cardiologist told me not very many folks recover from that. I also had a double bypass done. You are lucky to have your heart repaired before you have damage like me.
That said, I took my wife, daughter and grand daughter camping about 2 months after my big event. I had (at the time) a 27' bumper pull trailer and towed by an F250 V10. I had lots of help setting up and leveling but driving there was fine. Your situation may be different given what you camp in. It was difficult but it was important to me in my recovery process to continue doing things I enjoyed. Some things are off limits but camping wasn't one of them. Talk to your cardiologist and get their opinion. Maybe stay closer to medical help the first few times. Solicit help from your camping partner(s).
Now almost 10 years later I am still camping but in a new Class C. Sadly my wife passed 7 months ago so now it is just me and the dog. I had a second heart attack a year ago but I have recovered completely from that one. I am "Mostly Timing". That means I have an apartment but most of the time I am off somewhere in my RV. I have chosen to celebrate what I can still do, not to mourn what I can't. I wish the best for you and your recovery.
