First of all I would like to thank everyone for all the input regarding my questions regarding what is the best truck for me. The HELP threat got lots of response and advise.
Ok, pulled the plug and purchase a used 2019 F-350 4X4 short bed 6.7L Diesel. It only had 12,150 miles on it so figured is wasn't even broke in yet. Got a pretty good deal on it also so all ended well. Hope it preforms as my old 2012 F-250 6.2 gasser did, I'm sure it will pull the new Montana a lot easier for sure!!
Again, THANKS to all for all your advise and helpful suggestions!!
