Reasonably decent towed vehicles for a Class A

Thank you very much to all of you who've given me your thoughts and advice. I deeply appreciate hearing from each of you about this as it helps me better to decide what I want to do and how to go about it. I'm pretty sure I won't be DIYing this, though. I'd much prefer to have it professionally set up initially. I'm also very open to used vehicles since this new-to-me motorhome is used. I think we've bought two new vehicles in our lives. We tend to buy well-maintained used vehicles because they frankly hold their value better depending on what they are and they're usually far less expensive. You do have to do your homework with them, though.

For those who tow with dollies or trailers, do you find that you have trouble fitting into or finding places to stay that have extra room for the dolly or trailer? Does it complicate finding a place to stay? I'm not averse to towing trailers as that's the rig we have right this minute (we bought the motorhome in Florida which is where it is right now and we're in WA). We're both very, very experienced with towing trailers but not with a motorhome, yet.

Thank you everyone for your kind and valuable words. I appreciate it! BTW this is Laura. Tom doesn't post here. I'm more the RVer than he is but he goes along for the ride.
