How much will a Gasser Class A tow?
Good question and there is no FIXED answer
Generally the hitch receiver on a Gasser is rated 5,000 pounds
This assumes a Straight hitch. No rise/drop adapters. And no extenstions
(Those deices de-rate the receiver's rating)
BUT. wait there is more Oh yes always more
Your motor home has 3 Weigh numbers you need to know (Well you need two of them for this)
Max GVW (Maximum weight of Motor home. Full fuel tank Full Fresh water.. Loaded for travel should NOT exceed this number)
Next is MAX Combined Groos Vehicle Weight (GCVW)
This is weight of Motor home as above... PLUS anything you tow.
IN my case the MAX CGVW was 26,000
The actual weight of the Motor home as scaled fully loaded for a trip
In my case 22,000
Now take the last and subtract from the one above it and you get 4000 pounds IN MY CASE.
You will load differently from what I did so your figures will be different.
Also your Motor home may have a greater (or lesser) "Dry" weight. (the weight of JUST the motor home as it is delivered before addition of Food. Water. Clothing. Other stuff and occupants)
So Your question can only be answered by you
For how to weigh your Rig.. Three ways
CAT scales found at many truck stops (Be very careful they are not designed for 8 1/2 foot wide RV's WIll give you both axle and total weights.
With a FLAT segmented scale you can get Induvial wheel weights. (ALso axle and total)
RVSafety dot com has a weigh your rig link (Have not visited in several years)
You call them. (Have the make, model and size of your RV's Tires handy IE: Mitchlin XRV 22.5 x whatever) and they come armed with the Tire's weight chart
Then they use portable scales to weigh each wheel and tell you how many PSI should be in the tires.. NOTE I believe each tire may be different. Some say that all tires on a given axel should be the same.. I won't argue Just pointing out I disagree I can explain why.
They may have other suggestions.. I used this service.
Some Weigh Stations (Depart of Transport) leave scales on when closed
ANd you can alwyas buy a beer or two for a Weighmaster
But only the RVsafety folks come armed with the tire charts (you can download those from the tire maker_)
