Re: 40' MH with 20' boat
Last year I was at 32' RV with 21' boat & 26' trailer. RV is a Class C with the Ford 460 motor. I did two trips to the lake about an hour away.
For me ---
a) Stop & go in traffic, complete performance dog!
b) highway was OK. I just kept thinking I'm a big rig and I'm not going to worry about other cars, etc --- they are more nimble and probably want to get away from me anyways...
c) 5MPG
d) Plan out the gas stations ! You'll want straight thru lanes!
e) My launch area was a State Park and plenty of room to manuever.
f) I was able to see just enough of my trailer fender to back down OK.
g) At the ramp, you WILL be a spectacle and a gawking crowd will gather. Hero or Zero ! hahahaha....
h) Embrace the moment. You have all these toys for adventure -- and you'll be having one!
i) After launching, I parked the trailer, went to the camp site, and enjoyed using all the toys for 4 days.
The only thing I was concerned about was any panic stop or tight gas stations.
DO IT !
