Had a TT and then went to a MH. And NEVER looked back!
I have back and knee problems but it has never stopped me from doing all the things I like. That is until I bought a TT. What a pain, literally! :B
I do a lot of sporting events where the show might be in one spot on Saturday and another on Sunday and of course almost every weekend.
I'd still be there all alone in the lot hooking up, loading gear and then the dogs and their crates from the TT back to the TV. And then have to reverse the same process when I arrived at the next venue.
While my friends with MH's would be long gone on the road getting to the next event way before me and grabbing all the good spots!
IMHO, If you have any physical limiting ailments a MH is the way to go.
Pull in, park and open a cold one!
Then sit back and watch your friends unhooking, leveling, schelping their gear from the TV to the TT or FW, etc. etc. :C
