I assume with a BH there will be more than 2 adults onboard, more people = more stuff in the vehicle & rv, more stuff = more weight.
With a SUV as a tow vehicle the more seats filled = less payload for tongue weight.
I agree, you need to check the payload on that SUV then crunch some numbers. However there are 2 numbers that you DO NOT need;
#1 the max tow rating on your SUV, you WILL exceed the available payload & most likely the rear axle weight rating before you'll ever tow a rv near that advertised tow rating. This is simply a sales gimmick in an attempt to one up the competition & arrived at by the manufacturers under perfect conditions, not an everyday rv experience.
#2 The dry weight of ANY rv, that's what it weighed as it rolled out of the factory door, no batteries, no propane & no dealer added options it may get. Unless you are a rv delivery driver you will NEVER tow a rv anywhere near it's dry weight.
