The converter brand is WFCO...75 amp unit... will do a nice job for you... tire wise it looks like Alpine is now coming with Oracle G rated 14 ply tire... They had been using tire branded as Provider....
I think the Oracle name on the tire is related to Hispec but not certain
Previous reports I’ve seen on Provider tires were fine. While this tire is not oneof the better known ones currently used I’d see no problem with the 14 ply tire it’s coming with...
They still are using ST 235/80x16 and this tire is rated at 4000lbsmload capacity at 110 psi... I’d change out to ST235/85x16 for increased load capacity at 4400 lbs per tire.
But that’s my opinion... no idea about propane stove outside hookup...
