New to RV and buy my first RV

I did purchase the Jayco trailer above and had WD hitch installed. We went 600 mile round trip with any problems towing. We even had one day that we had cross winds and had slow down to about 55 - 60 but most of the time we did 65 miles a hour. I will say I don't think I would want to tow a TV much heavy then this one but that said I'm very happy with my purchase. Next weekend we are going about 700 mile round trip and looking forward to trip. We got between 9 and 10 miles to the gallon in tow mode so not good but not bad either.

Thanks for all the help!!!
